For the second time I have a weird feeling in the back of my head accompanied by a sense of my mind detaching from my body.  The weird feeling is like a pulse and then i felt like i moved 6 inches to the right of my body---but my body stayed in the same place.

I am 49, Female, pretty good health.  The last time this happened was a month ago.  I have a history of migraines (grade 7 and early 20's) ocular migraines w/vomiting (30's).
