did your ears make a weird pitched sound before?
did you try to move as this was happening and if you did, did it feel like your body wasnt doing what you felt it wanted too?
im only askign cuz i had a stroke.... and my body went numb and my eyes were all fuzzy
i would go get an MRI ... possible TIA , type of seizure or even migraine...??
talk to a neurologist see what they say...
It's time for a doctor visit my friend. Not to scare ya too much, but it could be cardio or stroke. If it happens again, ER immediately.
