JOE ROGAN revealed he had the "most psychedelic experience" while in his sauna on Sunday evening.
The UFC commentator has now shared the story in great detail with his Instagram followers, but admits he "hesitated" writing it down in words.
Rogan claimed he experienced "insane depictions of struggle and tragedy" from around 180 years ago.
He also revealed he began to hypnotise himself with the sound of his own breath.
Speaking to his 10.3million followers, he recalled: "Tonight I had the weirdest, most psychedelic experience in the sauna.
"I usually start off my sauna sessions listening to an audio book, and tonight I'm re-listening to 'Empire Of The Summer Moon' S.C Gwynne's epic tale of the Comanche Indians in the South West.
"I do breathing exercises where I breathe in deeply for six seconds, and then exhale for six.
"I got into my rhythm, and I started to get overwhelmed thinking about these insane depictions of struggle and tragedy, all of it taking place from around 180 years ago to the late 1900s.
"The stories of the raids, and the battles, and the massacres were both horrific and fascinating.
"I kept thinking, 'this was not that long ago'.

"Eventually I took the AirPods out and just got lost in the breathing.
"The images from the stories lit up my imagination, and the sound of my own breath began to hypnotise me.
"The sensation became really intense, and it felt as if a layer of whatever it is that keeps me from understand myself and the world around me was peeled away.
"Two words echoed in my head, 'love and understanding'.
"For the last 10 to 15 minutes these words and the ideas that came with them danced in my head to the sounds of inhaling and exhaling, transforming my thinking like a beautiful mind virus.
"When it was over I felt this overwhelming desire to just hug people and be nice to people.
"I also felt a slight dread that this was going to wear off.
"I hesitated writing this down because I'm absolutely I am not going to do it justice with just words, but I didn't want to forget that this happened."
In response, one fan said: "You reached a different level of connection. F***ing rad man congrats."
Another commented: "That's amazing man."
And one joked: "Think that's just heatstroke kicking in mate."
