Dream-like episodes. Anyone else experience this?

[Libby741]

I had an episode night before last where I felt like I was remembering a dream. After a couple of seconds, I was fully immersed in this memory/dream. I was aware it was happening, but couldn't pull myself out of it. It lasted for a minute or two, and when I came back, I was nauseous. Right before and after the episode, I felt tingling at the base of my skull.  After it was over, I couldn't remember anything about the memory/dream, just that it had happened. This isn't the first time this has happened. I've been having these "episodes" since 2011 (when I was 20). There's always some degree of familiarity to the "dreams." Kinda like deja vu. The one Friday night was the worst I've ever had. I saw my GP for them in 2011, and he wrote me off. Has anyone else experienced anything like this?

I've had similar but only after exercising, it's happened a handful of times. I thought maybe it was stress related because it first happened during a period of extreme stress and then recently again after a period of high stress. Did you ever find out what caused it? I didn't feel extreme nausea, but developed a headache and kind of like a dizziness unease.
