Sounds like some of the strange stuff i see when awaking from bad dreams... I have seen the occasional figure (one was a woman in a red mini-skirt),

With people or objects it may be that you awoke to fast for the mind to distinguish from the dream and had a waking hallucination. This also makes
sense with orbs as rapid eye movement will still be in action as your eyes open and adjust to the waking world. Sort of like a no mans land.
But on the other hand it could of been a real orb
