I am shocked to see The Gateway Experience mentioned. I specifically clicked on this story to post about it.

Anyway, TGE is a fantastic resource if you put the time into it. I've gotten to levels of meditation through it that still make me question reality.

On the one hand, I'm very much facts, data, and reproducibility oriented, and "I know" that everything I experienced was just my brain having fun.

On the other hand, WTF. Maybe I am more than my physical self, and there are alternate dimensions I can teleport myself to.
