It's the I've seen an entity - what does it mean - me too club.
collect the whole set of entities, right this way, club.
this is a sign of the times, and as life gets harder, more entities are going to get jammed into the memes.
eventually someone sees GOD, and all hell breaks loose. Any drug can do it, even no drug required. madness.
True, iirc it's a thing in the literature on hypnosis. People encounter a source of noise in their life, or a source of ambiguous sensation, and hereupon repressed material gets projected, something complex or simply a sense of loneliness displaced by a simulation of an idealized Other.
So there's the basic mechanism. In so far as psychedelics induce sensory noise, they therefore facilitate entities. For direct evocation the histaminergic Rayan mental organ needs to be blocked as to make the mind fill in the blanks. The only substance I can advise for this is Amanita Muscaria. Oh and DXM. High dose cough medicine has aliens. Not sure how @sekio could have missed them.
