Is DMT the key to hacking reality? (opens in new tab)

I guess I don't get how dimensions can be disconnected. It's true if you live in flatland and you move up into a third dimension you dont seem to move in flatland, but then if you wanted to explore the third dimension you would still move through the second, just as to exist in space one must exist in time. If you are moving through and extra dimension an outside observer ought to see part of that movement. (Granted I don't know what I'm talking about.)

Ok, so maybe I'd find it easier to believe if it was explained as some kind of wormholes​ opening up to our senses that allow us to occupy some kind of Avatar from this point in space.

I guess you could have two trippers meet in this space and exchange information. That should be testable.

That is kind of a strange question for something that changes the structure of your heart valves. I'm going to go with "yes", but I'm no cardiologist. You can get heart valve replacement surgery, which might be "permanent" depending on your viewpoint. Death is also permanent, but you were going to do that anyway.
