Hi and welcome to NeuroTalk.

Have you talked to your Doctor yet??

Some of what you described sounds somewhat the same as some people can experience after a concussion. I've, thankfully never in my life had the experience of having a drink spiked (if that's what you mean by laced) so I don't know how that would feel. I doubt that the side effects of that would last all this time though.

Have a read in the
Traumatic Brain Injury & Post Concussion Syndrome Forum

You'll find some very recent posts there about that odd feeling when our surroundings seem unfamiliar. Derealization / Depersonalization. Have a read and see if that's what you're experiencing. You can search each forum using the Forum Search feature below if you want.

Check out the Sticky threads at the very top of the forum. They contain information and useful websites and other helpful topics.

You really should go see your Doctor if you haven't already.

all the best to you.
