Hypnotic Imagery?

A few days ago I was concentrating on staring under my eyelids and then I saw a face that was 3D, but it looked like a cartoon and it was wiggling like jello. I opened my eyes because it looked weird. It was very clear, but now I can’t remember it. Was that hypnotic imagery?

Yes. You could’ve used this to go into a WILD by watching the hypnagogic imagery (that’s the real name) and eventually be draw into a dream.

I guess you mean hypnagogic imagery? Could be. Though hypnagogics usually don’t appear if you concentrate on them. They’re more a result of brain mechanics which happen after your body fall into a trance state of full relaxation. It could also be random imagery, induced by your concentration and light patterns underneath your eyelids.
