Derealization is something I've been experiencing for awhile now. A sense of unreality, like everything is a bad dream. At times I could find myself thinking perhaps committing suicide will just cause me to wake up. Maybe the act of suicide would wake me up so that my last moments of existence would be perceived to have realness.

I've not experienced the distance from events you describe. Perhaps mine is more persistent, or it could be less intense, or a different occurrence altogether.

I tell myself it's the Benzodiazepine I'm in withdrawal from that's causing this, but I'm uncertain how long this disconnect from reality has been going on. It could be that the benzo just made it more pronounced, that after I've tapered off it I'll still have to deal with wondering when I will wake up.
