I did DMT a couple times, What i experienced was this:

I was aware that I was on a plane of which there are several.
It was very pretty but I was the only one there. I knew there were other planes and I wanted to go experience a nicer one but I was stuck.

I would describe it something like this.
Consider an empty egg carton with the lid torn off. You are in one of the 'cups' of the carton. The cup is a plane. You know there are other cups/planes but you are stuck in the one.

I would love to take a trip again but I want to be more in control. I want to choose what plane/planes I want to visit.
I've done that in OBE's without DMT and I learned to just pass by the lower realms/planes.

Working on meditation these days.
