The question is very small, what does the sentence "Lose yourself" mean?
I searched on internet and got many different meanings. Two of which are quite contrary to each other. One is,
"preoccupy yourself with something other than yourself".
The second is,
"to free your mind from worry"
If someone preoccupies himself with something then he is not going to relax at all.
I found many different meanings, e.g. here on Quora.com and here on yahoo.com. I guess it is a subjective phrase, which can have different meaning depending upon the context.
So the question is:
Does its meaning depend upon context, dialect in which it is used, or something else? If it has a fixed meaning then please tell that. Is its meaning opinion based? When is it used, that what meaning does it convey or in other words what is its purpose?

Probably you refer to a song by Eminem. Text here:
http://de.urbandictionary.com/define.php?term=lose+yourself
In the first line we have "You better lose yourself in the music..."
Here to lose has its original sense as in "Damn, I've lost my keys." OALD has "lose yourself in something" as an idiom meaning Forget everything else and become one with the thing you are interested in.
As a maxim of life of dubious value.

You'll find "to lose oneself in sth" at the bottom of the page (phrasal verbs).
