John Keel & Jaques Vallee

"Read John Keel and Jaques Vallee.
Passport to Magonia/Revelations by Vallee and Operation Trojan Horse by Keel are a good start if you want to shit your pants and suffer nightmares for a month." - Anon

These authors keep getting recommended and I keep forgetting to read them. I'm making it a point to remember this time.

Also? I'm more and more convinced that both aliens and the supernatural are interdimensional in nature.

11-dimensional organisms? Why not. Plenty of room for intelligence to evolve too. There could be millions of worlds overlapping our own; no FTL space travel required.
