In about a month, when I get back from a family vacation, I am going to try and stay up as long as possible.

At some point, if I stay up long enough, I will start hallucinating, sort of like, what it's like to be in Sleep-Paralysis, except without the paralysis affect.

Why am I doing this? Well it's summer and I just want to see what it's like. Right now I'm on about 30+ hours of no sleep, and it's not a big deal. Once in a while, if I'm sitting down, I'll just zone out while trying to look at something and have thoughts race through my mind and feel slightly fuzzy. Easy to snap out of though. I'll get to about 38 hours, then I'll pass out on a plane ride.

But, I just want to ask in advance, has anyone tried this before?
