Shadow Figure Or Guardian Angel?

I've searched this many times, with no luck finding anything on it. I'm not sure where else to post and ask questions. Here we go:

When I was young, maybe 5-6, my family lived in a three-bedroom house. We had a few guests over one night, (my sister, her boyfriend, my sister's friend and my sister's friend's boyfriend) and the usual people who lived there were my mom, dad, and myself. My parents had a king sized bed, so my sister and all of her friends got to sleep in that bed all together. My parents and I squeezed into the twin size hospital bed we had for my grandpa who would soon move in with us. I woke up, maybe 2-3 in the morning, to go get more milk. I had the cutest cup. It was an elephant. His head came off and you poured the drink in, and his trunk was a straw! (Completely useless information that cup was just so cute.)

My bedroom was right across the hall from where I was sleeping with my parents, but at that time I did not sleep in my own bed, and I'm glad I didn't. As I walked out of the bedroom to get some more milk, I looked into my room. I saw a large figure, with huge glowing blue eyes. I couldn't really see a body, or even the shape of a head. I did see two huge eyes. Glowing with no light to illuminate them. I never felt scared of it. I stared at it, as it stared back at me. Now I'm not sure if it seemed so large because I was so little, but from what I can remember it looked to be as tall as my door, a standard door. The eyes of this were probably the size of a baseball each. Glowing white with blue as the color. Almost like someone was holding a flashlight behind them. Like I said I never felt scared, I thought it was probably a human, because at 5 you don't realize eyes that big are extremely abnormal. I continued on my mission to get more milk, and I guess things slowly started to process as I did, because when I was walking back to the room I shared with my parents, I was afraid to look into my bedroom.

I woke my mom up, and told her someone was in my room. She got up out of bed and looked. We found nothing. I'm 21 now and I still wonder what I saw that night. I don't know how to explain it to people, and half of them tell me it was all just a dream. I'm sure it wasn't, because when I woke up for good later that morning, the milk I spilt was still left on the kitchen floor, and my cup was full.

I've had small paranormal things happen as I've grown up. We moved to a new house and you'd see things out of the corner of your eyes, or hear people talking, the common stuff I guess. I've never seen those glowing blue eyes again, and I'm not sure I want to. I now live elsewhere with my fiance and I still feel things have followed me into my adult life. I feel uncomfortable alone in my house now and still see things. I'm not sure if something is attached to me, or if it's just the places I've lived. The blue eyes have never returned though.

Anyone have an idea what I saw? I told myself it was my guardian angel for the longest time, but now I'm ready to get to the bottom of this.
