I wake up unable to move, its like I'm being forced down, what is this?

Sleep Paralysis. Sleep paralysis is a sensation of being mentally awake but unable to move. Common causes include inadequate sleep or irregular sleep-wake hours. If the problem persists despite maintaining an acceptable sleep schedule then consider an evaluation by a sleep medicine specialist.
Consider narcolepsy. The narcolepsy symptoms may include daytime sleep attacks, vivid dreams (hypnagogic hallucinations), cataplexy, and "sleep paralysis". So just to address this possibility, get some genetic testing, and perhaps overnight sleep study, but eeg may suffice.
