One lesser known psychedelic, Salvia Divinorum, when taken responsibly and with a measured dose derived from incremental experimentation, tends to bring a person into the weird world too. Lots of beings, lots of entities.
That wasn't the case for me when I experimented with that in high school years ago. Definitely no hallucinations or anything really close to that, though the extracts will put you in a weird (and very uncomfortable - it is not fun; about as fun as being tickled against your will) world for a brief period of time. Really the only thing that makes Salvia Divinorum worth trying is the "after glow" affect that lasts a couple weeks that can alleviate depression.
