Sorcerous Origin: Dream Conduit
Sorcerers whose power arises from dreams are rare and as varied as the dreamscapes that empower them. Such sorcerers are often known as "Dream Conduits" due to their ability to reach from the waking world into the dream world and to bring the stuff of the dream world back.
Artist of Sleep
1st-level Dream Conduit feature
You are attuned to the magic of the sleeping mind. Neither magic nor poisons can force you asleep against your will, and you learn an expanded list of spells given in the Dream Spells list, below. These spells count as Sorcerer spells for you and become known for you at the associated levels, but they do not count against your number of spells known.
When you cast the sleep spell using a spell slot, you may optionally spend a number of sorcery points no greater than your level in this class divided by three, rounded up, to add 2d8 per spent point to the sleep spell's roll.
Dream Spells
- Level 1. sleep
- Level 3. detect thoughts
- Level 5. bestow curse
- Level 7. death ward
- Level 9. dream
Dream Sight
6th-level Dream Conduit feature
You are so practiced in the crafts of dreams that you can observe the dreams of others that sleep. You may spend your action and 2 sorcery points to force an unconscious creature you touch to make a Wisdom saving throw against your spell save DC. If the creature fails the saving throw, you may give it a single question or prompt and witness its dreams about this prompt. The information gained from this feature should be approximately equivalent to that gained from a failed saving throw against the detect thoughts spell. Additionally, if the creature fails this save, you may optionally spend 1 additional sorcery point to cause it to be either charmed or frightened by you (your choice) for 1 minute, starting when it awakens.
Once you have targeted a creature using this feature, you may not target the same creature with it again until you have completed a short or long rest. Creatures that are incapable of dreaming, such as oozes, are immune to this feature, but creatures that can dream (but do not necessarily need to sleep or dream), such as elves, are not.
Dream Step
14th-level Dream Conduit feature
Your knowledge of dreams has grown such that you can now reach across the Dream and use it as a path between dreamers. When you begin a long rest, you may choose a number of willing creatures no greater than your charisma modifier (minimum of 1) who are on the same plane of existence as you. Creatures incapable of dreaming cannot be targeted by this spell. You and all targets fall into a deep slumber and appear to each other in a shared dream, which you control. Dreamers leave the shared dream and awaken if they are awaked normally, if they choose to leave, or if they take damage, and if you awaken the dream ends. If 8 hours pass, the dream ends, and you may choose one creature who is still in the dream (including yourself); all willing creatures still in the dream are transported to the locations nearest the chosen creature and awaken there.
The use of this feature does not prevent you or any target from gaining the benefits of a long rest during the shared dream, but every creature transported using this feature, including yourself, gains one level of exhaustion upon waking.
Additionally, you cannot be targeted by the Dream spell against your will.
Rending the Veil
18th-level Dream Conduit feature
Your explorations of dreams have given you the ability to tear apart the boundary between it and the waking world. As an action, you may spend 6 sorcery points in order to fall into a deep slumber for one minute from which you can only be awakened by taking damage or by choosing to awaken at the beginning of your turn. You become unconscious, and until you awaken, your dreams reach out from you to fill a sphere with a radius of 60 feet centered on you. This area becomes difficult terrain for any creature of your choice, and whenever a creature except you begins its turn in this area, you may optionally choose one of the following:
- You may immediately grant the effects of the sanctuary spell to the creature.
- You may immediately allow the creature to move up to 10 feet without spending its movement and without provoking opportunity attacks.
- You may give the creature up to three of your sorcery points and allow it to use any meta-magic you know when casting spells on its turn. At the end of its turn, any excess sorcery points that the creature cannot normally hold are lost.

This subclass is a bit weak for practical play
Most play happens in tier one and two, a little in tier three, and next to nothing in tier four. So unless you have a very unusual campaign, your level 1 and 6 power will matter a lot, your level 14 power will a little, and your level 18 power is something that looks cool in a rulebook, but rarely sees the light of day and does matter less for the subclasses strength. Here the first feature seems to be balanced in tier one play, but loses steam later, and the second feature is relatively weak.
1: Dream Spells: This part is balanced -- there are several sorcerer classes in Tasha's that have a comparable feature with more selection on it, typically you can pick from two options at each level, so selection is slightly weaker. Sleep early is great, but already is a sorcerer spell. The list also does not make up in power for the more narrow options, for example bestow curse is a subpar spell. Dream is a great thematic fit, of course. You could copy the general language part from Tasha's to be closer to the published variants in wording how the feature works. The extra hp on sleep help to even this out - typical early opponents tend to have no more than a dozen hp, so this adds a little punch early on, and there is no save. The hp grow quickly by tier two, an ogre e.g. has nearly 60 and would need 13d8 to put to sleep.
6: Dream Sight. This seems pretty weak to me. In normal play, by the time a creature is unconscious it is often because you opted to knock it out instead of killing it, so little combat applications, and the number of adventures where you would sneak up on a sleeping creature to gain some intel this way seems rare. So it might help as a interrogation tool. Detect Thoughts is also on the sorcerer list, and creating a spell slot for it would only cost 1 more Sorcery point, at no feature cost than a known spell. So this for the most part is like one more known spell that can only be used very situationally.
14: Dream Step By now you can expect your Charisma modifier to be +5, so this will affect five creatures. Since the other creatures can leave any time, this has no offensive capability. I think it is kind of useful for planning purposes, but at the same time, the party normally can just talk to each other, and whichever NPCs is off remote, you could contact with dream already to achieve the same thing. The teleport aspect can be useful to transport your group to a known NPC, so I think this is OK -- it will not get you out of a sticky situtation like Teleport would which is available at the same level. You also need a way to protect the team, if all of you are sleeping, or you may never live to see the day.
18: Rending the Veil This one seems to be powerful to me, even if it costs a third of your sorcery points. I can see this leading to all kinds of Shenanigans by giving sorcery points and metamagic to classes that normally do not have them, and creating difficult terrain and giving all your allies Sanctuary and increased speed and mobility each round is good. At the same time, the cost of not having any actions yourself and being vulnerable because you are asleep is still pretty steep, so I don't think it is broken. And, as I mentioned in the intro, this power is the least relevant.
You did a good job at not falling into the much more common trap of creating an overpowered munchkin fantasy. I would rework this to have a bit more oomph, though.
