What does the hand icon indicate, when using Witcher Sense, especially when it appears over tiles in caves

the-witcher-3

In Witcher 3, sometimes in caves, on top of tiles there appears a hand icon, which can only be seen when using Witcher Sense. It's an open hand with the palm facing downwards.

Anyone know what it means? I've seen these a few times and have tried doing everything I can to interact with them, but nothing works. I hope they aren't important.

Sounds like the same hand that appears over bee hives, I think it may indicate indirect interaction.

With bee hives you have to use Igni to kill the bees and knock the hive off so you can then interact and get the sweet sweet honeycomb held within.
