More likely DMT. It’s a chemical that exists in almost all living things to some degree, and what makes humans dream.

A lot of people have reported hallucinations of eyes and machinery. From the wiki page:

Strassman also argues for a similarity in his study participants’ descriptions of mechanized wheels, gears and machinery in these encounters, with those described in visions of encounters with the Living Creatures and Ophanim of the Hebrew Bible

There are many, many forms of “angels”, the one you drew is an Ophanim. Angels that hollywood portrays, humanoid with wings, are Malakim. Technically both are biblically accurate!
