Ok so I woke up just fine, but a couple of hours after waking I got the same sensation of disembodiment.  It's still occurring at night although not as intensely.  Today though I got migraine auras in the temples with a mild headache.  I was woken this afternoon with my left foot hurting like cramp on the top.  I've forgotten to take my rheumatism tablets for 4 days do it's no surprise.
