Did I see a ghost, demon or an angel?

For the past two weeks, I have been feeling someone touching me during my sleep that I would jump up to see what it is each time that happens. The touch feels like a physical being trying to wake me. And when I wake as in responding to the touch, I would see no one.

This morning, it occurred again, and when I responded to the touch, there was no one. Then I went back to sleep. A few minutes later, I felt the touched again, and this time I decided not to immediately respond to it. I stayed there with my eyes close, then after a while, I popped my eyes open in hopes to catch the phenomenon, and this time, finally, I opened my eyes to briefly see something. The "something" quickly turned into a VERY bright white light, and I kept my focus on it, I saw only two wings flying upwards towards the ceiling until it completely went through the ceiling. This occurrence lasted for less than 2 seconds. It was VERY brief. Only thing I could recall seeing were two wings.

Could this be a demon? Ghost? Angel? What's your thought?
