Helperman

First(this one was about a week ago), after I became lucid, I decided to fly around, and I saw two mountains, I carefully chose this taller on that had a weird pattern, and then fly around it and managed to make a cave appear on it and I flew into the cave and saw a different world.

Second(last night), shortly after becoming lucid I was swallowed by a giant whale like sea monster, but I willingly went in and then sort of phased into it, dispersed my body into dust so I didn't have a physical body, and then became the giant whale thing, and had fun swimming and eating fish.
