Does anyone else get that feeling? It's so hard to describe, but I feel it most when I am still. It feels like the mildest form of almost fainting or kind of like when you start to fall asleep sitting up and your head feels like it's falling and then you jerk back. I don't jerk back but I get that strange sensation of sort of drifting or floating through my head/brain. It seems to be worse when I'm lacking sleep, overdone, more stressed or pms/start of my cycle. It scared me so much I had brain tests done and my brain is fine! I guess that's good, but then I'm guessing it's hormones causing it, most likely my adrenals.
