So were you sleeping then or were you awake? What this could be is you being in a crossover state of sleep and consciousness. Happens all the time. Any good Psychology book explains this.
It usually occurs when the brain is tired and fails to enter REM sleep. The product of this is usually something like you described, only it is usually much worse, with severe nightmares taking place...
I hope this is what took place for your sake anyway!
