I don’t know how much of that is real, venting, shitposting, or RP, but you should not be attempting to give yourself a head concussion, and you should not be encouraging such things.
A head concussion is not going to lead to concrete memory loss or “lost time” like on TV, it’s going to bruise your brain and lead to diminished mental faculties, possibly permanently.
If you’re suffering issues that you believe can only be solved by not being awake or not remembering events, please talk to somebody with training that may be able to help you get past what you’re going through.
