Well, you could do practically anything in a lucid dream. Considering its your own mind we're talking about. So what your describing shouldn't be hard. Just need to learn how to do it.

And I know that feeling, the night can't come fast enough! I still get that. Even after half a month or so.
If you really wanted to you could try WILDing for a nap.
(If you'd like WILDing explained, just ask me or someone else, its a popular way to nap)

Anyways, welcome!
