I've been "blacking out" and I can see and hear things but can't control my limbs, is this a neurological problem?

See your doctor. It depends on when this is happening... If it is related to sleep onset or upon awakening... This could be narcolepsy... These symptoms are not normal. You should see your primary care doctor and possibly a neurologist.
Syncope. Sounds like you are experiencing syncopal spells. They are usually brief and self limiting. Speak with your doctor as there may be cardiac causes in addition to neurologic and emotional causes.
