Migraines Vivid Dreams

Whenever I am about to get a migraine, my prodrome period includes hypersomnia, with intense, vivid dreams. The dreams are not surreal or bizarre, but more like watching a movie of another life. What I mean, is the dreams seem to be about me in that I am involved in a first person type feeling, but it is a totally different me in a different place and time, and the events play out vividly like a movie because the situations, places and times are not familiar to me in my everyday life. Events seem very real, and I can recount the dream in detail when I wake, which is unusual for me. The dreams leave me feeling very emotional, like I have a vision or glimpse into a prior life. Please keep in mind this is coming from someone who is agnostic at best, cynical and no serious interests in spirituality. But I can remember all the dreams before migraines and the only way to describe the experience is leaving me with a feeling of having experienced something spiritually significant. I was wondering if anyone else has experience, insight or can relate to any of this? Thank you in advance.

 

I don't know what to make of that link or see how it relates.
