Seems there are three possible scenarios that could be what happened.
A) He lost touch of reality as said and didn't realize what was going on in reality.
2) He wanted to jack-off and didn't care if anyone was around, then used the I was too high excuse.
D) He Hoped that someone would join into his fun.
.
D: I really doubt so.
2: I know this friend quite good and I'm pretty sure that's not the reason
A: This seems most likely form what he said and from what have I seen during the trip.
He masturbated quite discretely under the blanket and turned away from all of us. I knew that he was in his own mindset at the moment so I didn't want to bother him or others with what he was doing. I just turned around and let him be.
That happened to me and this friend but a little more intense to him I could say. It's very interesting =]blacking out while some sort of autonomic process keeps the eyes open and the body moving about but little else.
