Unsure with unclear memories

For a very long time I have been in denial on what these tiny memories I have when I wake up in the morning. For one of the most recent one I have was a few months ago,I think in early June 2010. I was at my mom's house near central Wisconsin for a few days with my two young daughters. I was woken up around 1 am in the morning with a hand coming towards me and I grabbed at it and pried it off my arm. I kinda remembered struggling a bit and had fear for my daughter's life. From that I don't remembered anything. I woke up that morning with my arm feeling a little sore and two tiny bruises on my arm. I thought that was more important then this next one I'm going to mention. Two weeks ago I fell asleep on my mom's couch with my 2 year old. I didn't have anything exciting happen but I did wake up with two bruises on my arm again and it felt like someone grabbed my arm tightly. I also want to mention I don't bruise easily either.
There were numerous of times within the years when I'll have weird dreams that someone is trying to take me out of the bed and end up waking up with bruises on my arm. Not sure having to wake up without my socks on has anything to do with it,but that's how I wake up from those type of dreams.
Another memory I have back when I was around 14 years old, I had a dream of kicking a small grey alien in the face as it was reaching for me from the foot end of the bed. From there I woke up after that scared out of my wits and feel back to sleep reassuring myself it was just a nightmare.
The first memory I have had back when I was 5 years old. It was the middle of summer and my family was up late as we talked and joked around. I remember sitting on the couch with my mom was we were eating pie she made that day. I remembered lights from out side and a light was shining down from the sky. I thought the lights looked red or orange. I didn't see it from the sky since I was in the house. My dad decides to go outside to go check it out since my mom told him to. From there all I remember was my dad looking up in the sky.
In the past I have asked my mom about this and it seems to frighten her to even talk about it when I was younger. I brought it up to her when I was 12 and she just told me she had no idea what I was talking about.
This is all I got to say,it could be just my mind having me think things and it's paranoia. Who knows but it was nice just to share this with people. Since I don't really like telling people I know about this and have them think I'm a total nutcase. Oh yeah forgot to mention this all happened at my mom's house with all these experiences. I don't have them anywhere else,but here.
