I am seeking medical advise about these recent episodes where everything seems really surreal. Its not light headed, and not headache. It just feels really strange, it feels like early signs of a seizure or a stroke or something. Its hard to explain. I used to use substances when I was younger, and I still smoke cigarettes up to this day. That is the only explanation I can think of as to why this might happen. But that was along time ago. I was wondering if this is a common medical condition, or something psychological. It is something new and worrisome. Thanks for your advise.
