Today, while in the grocery store, I went from being clicked in to feeling completely high. Things felt as if they weren't real, my memory and thinking skills evaporated into thin air, and I actually felt as though I couldn't walk properly because I was so disoriented.  My friend who was with me said she was asking me questions but I wasn't answering--I was just staring into a blank space. I don't remember her asking me any questions. Also, when I got home, I realized I bought a bunch of things I don't remember putting in my cart. Is this dissociation? I'd been having a rough day, but when these feelings hit me, I wasn't experiencing any strong emotions in that precise moment. This feeling happens to me occasionally, and I just don't understand it entirely.
