I had in interesting trip...

I didn't have too many visuals. But I lied down around 1am, closed my eyes time went by so quickly. 3 hours felt like 5 minutes. The next time I had opened my eyes, the sun was coming up.

I also felt like I had no thoughts for the last 6 hours or so. Just nothing at all. Extremely clearheaded.

Have any of you experienced something similar to this?
