There are several type of entity experiences on DMT.
In my experience the most interesting ones are like this:
The room you're in deconstructs itself into constantly moving non-euclidian geometry that is both somehow the room you're in and is also this novel geometric environment that is constantly shifting around
The entities kind of bubble up in this geometry and are not separate from this geometry but they are part of it, as in, this geometry is both the room and the entity
They seem to be able to manipulate this environment and they will basically wave it/the geometry/themselves around in your face like they're trying to show you something. It's also slightly unsettling because you can't hear them so it's like watching a tv on mute.
For me this is almost always coupled with a judgemental feeling, like I've made a mistake, or they're like what the fuck are you doing here idiot, their faces are always like some unsettling geometric :O face. The theme is usually a clown or spaceman or space girl.
They can also appear in traditional astral forms (emerge and interact with your environment), I've met several catlike entities this way, and some of them really like mocking you (my struggle is pornography and sometimes purple space girl shows up and bends over and shows me her butt before laughing at me)
There's also the full breakthrough where you bust out of 3d reality for 15 seconds and and you're on some sort of table or bed with interdimensional mice people gathered around you like HOLY SHIT HE BROKE OUT OF THE MATRIX
Or the rainbow machine gnomes who have various tools like things that reach inside of you, or show you how to paint with God's love
Or the ones that show up in a huge group to show/tell you about the dimension of constant orgasms (where the fabric of reality is pleasure)
