Replying to Memory Dreams

So lately I have been having these super fucked up dreams where I take on a completely differnt identity, or like none at all and i don't know who I am or where I am. Now when i wake up i still don't know who or where I am, yesterday it took me a good 1/2 hour to figure shit out, it was super intense.  Has any one else had anything liek this?    
 
Has anyone else had something like this where you have long intense confusing dreams and when you wake up you still don't knwo who or where you are cuz the dreams where soo crazy?
