Towards the end of a rather normal dream (a normal dream for me is extremely abnormal to most people), I was standing in a dark room.  I was lookin into a reflective glass, probably a window.  I then saw a shadowy, thin figure standing some distance behind me in the reflective glass.  THe feeling I got from this being was extremely strange.  It felt as if this being was not just simply part of my dream.. it seemed as if this being had its own consciousness, it seemed as if this being entered my dream purposely. 

I did not like the feeling I got from this being, so I decided to leave the dream.  The room skewed, my mind traveled off quite a distance.. but after a few seconds I saw an image of the shadow figure again, and it seemed to be following me. 

Finally I woke up and I almost had a heart attack.  Everywhere I looked, I saw the image of alien heads.  On the walls, on objects in my room, and even on my girlfriend.  However, I certainly was not dreaming.  I waited about 30 seconds, and the images faded away.  I dont know if that figure that came to me in my dream had some connection to the images I saw upon awakening.  My guess is yes.

Dude:

I've had lots of odd experiences and I'm still alive and kicking.

Here are three possibilities for what occurred.

1. Your mind created the whole thing.
2. An unfriendly being made an appearance, but couldn't do anything to hurt you.
3. Your spirit guidance, perhaps your higher self, created the experience in order to let you know that you don't have anything to worry about.

How does your spirit guidance let you know that you don't have anything to be worry about by creating such an experience? Because they created a no lose situation.  If your mind caused the experience, in the end the experience didn't get the best of you.  If an unfriendly spirit is responsible, it couldn't get the best of you. If your spirit guidance created the experience, it let you know if a very strong way that you're safe.

As long as you chose to live according to love and light, you should be well protected.

I remember that in a past thread you stated that you used to be afraid of aliens, but then got over the fear. I've found that sometimes we believe we got over something when we haven't.  A fear gets repressed for a while.  Sometimes we'll create an aspect of mind without consciously choosing to do so. Perhaps we'll read what a guy like David Icke has to say about aliens, consciously dismiss it, but another fragment of our mind takes what David has to say seriously, and creates a mini belief system that eventually has to be dealt with. The fact of how you became afraid during this experience suggests that you haven't gotten over your fear of aliens completely, otherwise you would've responded differently.

If I had to guess I'd say that your spirit guidance created the experience because 1) the being appeared during a dream; 2) because you saw a bunch of alien heads at the end of your experience (Why would aliens appear in such a way?) 3) if you have a fear to deal with your guidance is going to do something to help you get rid of it; and 4) it reminds me of some of the experiences my guidance has created. Whatever it takes.

I found that one's higher self/spirit guidance can create all kinds of experiences.
