What is the creepiest thing that's happened to you personally that made you question reality?

A 4 day, non stop, cluster headache attack.

Apparently your brain stops to to make memories when you're in this kind of pain.

So you know you're in pain and you know it's another hour, another day but you don't seem to remember having the same pain an hour ago or a day ago.

So if the pain last 4 days you don't really remember the last 4 days even happening. You know it started Friday morning and you know it's Tuesday when you're talking with your neurologist and the pain has become tolerable again. I knew I didn't have a cluster free moment but I couldn't remember the pain. I couldn't remember when it was moderate or severe, I couldn't remember who visited me, I couldn't remember what medication I got,...

I just remembered flashes of incredible pain and having a lot of trouble breathing because every muscle in my body was tensing up.

After a few days I started even doubting it really happened. Now the only thing I remember is that I was in the hospital and that everybody was fucking freaking out.
