This is driving me nuts. Do, or do I not have dissociation?

A few months ago I did some weed which I supect was laced with PCP. PCP - the drug which I sworn to never touch from the very instant I heard of its existance.

The scariest $#%^ happend. But no. I had no sense of invinsibility and super human strength, no urge to get naked and was not numb at all. I was just floating around in my mind.

So. Eversince I feel like I never really got out of it. Eversince I feel I'm partially stuck. Basicly I feel like I'm only half existing, half conscious, half aware. I feel the world is a dying hologram. I might be in a coma. I might be one of the few survivors of a world destroyed by a nuclear world war, nigh to death on some alien mothership keeping me in a computer controlled coma to save an almost extinct universal spieces. That weird drug experience might be my mind jumbled up from the 'end of the world' experience. Although I know that is almost certainly not true, it doesn't feel that way. The world feels anything but convincing and really 'real.'

Yet at the same time as scary as it is sometimes, it's warm. It is comfy. It dampens the world's impact. I have social anxiety but now it's somewhat easier to deal with. I'm not that hyper aware anymore. Like I crawled into a cocoon. Life being nothing but a dream sure helps in dealing with it.

It's ok when I had a good night's sleep. But when I'm tired or worse when I'm tired AND have to do repetitive things over and over(for work), I will almost lose my mind. I will get confused and slightly disorientated. The world will look like a dying hologram printed on my eyeballs instead of just the usual 'fog' or 'dreamy' feeling. Last time I was sawing these rubbers for truck windows (about 600) at a buzz saw when I suddenly couldn't really pinpoint the saw's location. It was just a HUGE blur (not a visual blur mind you). So I had to stop for a few seconds to get back to 'senses.' When I was done I was walking on 'air' again. I felt like I was experiencing the last flikkering glimpses of reality. Like a old TV it was to shut down any moment (I knew this wasn't true but that's how it felt). A dying hologram. Like I can't see but I do see.

Am I brain damaged or do I have dissociation?

You should go to a doctor for an official diagnosis. If it is a psychological disorder only a Psychiatrist will be able to evaluate it. From what you describe it sounds like it is not a normal experience....see a doctor...even if it's a psych doctor or regular...no harm from it
