The Greys on the Big Island

Aloha all! I'm a 27 year old man currently living in Los Angeles. The reason for this and most likely every time I have moved is because, well, I think my sub-conscience is keeping my running.
The first thing I remember was when I was about 5 and I would have these two types of incredibly intense energy almost seemingly enter my body randomly and would be so intense that it would make me cry. It's hard to describe but it was a very soft and a very rough energy that I could even see when I closed my eyes. I was never able to explain it.
I grew up in the woods with my 5 siblings and parents in a small cedar cabin. The first experience I remember was when I was 15. I awoke from my bed one night with the cabin flooded in blue light. I immediately saw a small, about 4' tall, grey on it's hands and knees starring at me. At the foot of the bed was a larger grey at about 5'5" also starring at me. The larger one using telepathic communication, and it told me everything was ok, they were not there to harm me, and to follow them. I did. Against my every instinct, I got up out of bed and began to follow them. As we got to the doorway something came over me. I had an intense surge of adrenaline and pounced onto the smaller grey grabbing it by its neck. I slammed it against the wall and banged its head twice. It let a very high pitched noise out of it's mouth and I stopped and looked up at the taller grey. It looked at me and I blacked out. I awoke the next morning in my bed and suddenly had this memory run through my mind.
I have never had realistic dreams or nightmares. I don't talk in my sleep and I have never been know to sleep walk. I have always lived intimately with people and have always been a very deep sleeper.
The second time was only a couple weeks later and again I awoke with the cabin flooded with blue light. I slept in a loft on the second floor and had a feeling there was something downstairs. I got up, looked over the railing only to see 6 greys surrounding my two youngest sisters bed. My parents were next to them and I thought all I had to do was scream and wake them up. As soon as I began to scream they all looked up at me and again I blacked out. I awoke in my bed the next day again remembering this the same way as the first.
The third time was about a month later and to me was the evidence that this was real. All I remembered was walking out of the cabin into the huge front yard at night. There was a blinding white light consuming the entire front lawn. I looked up and saw a large saucer shaped object with flashing multi-colored lights and I thought, "Oh my god that's a UFO!" I don't know what was controlling me but I continued to walk towards the light in the yard. I awoke the next morning only remembering this. I lifted my head and it was stuck to my pillow. I peeled my head off and turned around to see my pillow covered in dried blood. I felt the back of my head to find a gash running across my neck right below my skull. I pulled the sheets off to find myself naked and covered in scratches and bruises. I freaked out and for the first time told my mom about all three instances.
Every time I go back home since I first escaped at 17 years old I have had intense experiences.
Since then I have had an incredible change in my outlook on life. Peaceful, vegetarian, humanitarian, animal and nature lover, compassionate, curious, restless...I feel like I'm waiting for something to happen. Like my life mission is waiting to begin.
Writing this has given me intense chicken skin running up and down my body non-stop right now. I have never written this down before and it feels really good. Unfortunately, I have people trying to read this over my shoulder and I would really not scare anyone I know about this. So, please give me feedback. I have other experiences to share but this was the beginning, and it felt good to put down!
