Weird Dream regarding aliens - thoughts?

It was actually a series of dreams, but I'm having trouble remembering some of them, but there were two constants the typical "grey aliens" and my forehead had this intense throbbing that kept waking me up throughout the night.

The throbbing wasn't painful, but it was extremely intense and it was both during my dreams and while semi-awake.

Anyway, here is the segment of the dream that really stood out to me:

I'd looked down at my penis/genitals for some reason and it had been partially shaved and the remaining hair was very sparse. I say "shaved" but it didn't look shaved - the hair was just gone.

I then noticed all my freckles/moles were gone and my skin was even more pale than it normally is. I looked up into the mirror and slowly I was getting more pale, my limbs elongated and I was slowly changing into a grey alien, but still looked human too.

I turned around and there were several grey aliens in the room that I hadn't noticed - they were all looking at me and I think "talking" but I don't remember what they said.

Thoughts?

Oh, and another thing, during one of the times I woke up from my forehead throbbing, I kept seeing quick flashes of images, like photographs that were black, white and very realistic - it was far more real than my normal visualizations. The images cycled quickly and were of people I'd never seen before.

I'm not under any particular emotional stress or anything so I'm not sure why I had such a rough night.
