My father woke me up one day (this was in the middle of summer) and asked if I needed anything from the store. I said no and went back to sleep while my dad and sisters went to town to get groceries. I later woke up around noon that day and looked out the door window and I saw a 7-8' tall olive green skinned reptilian-like humanoid alien with a normal sized head and long limbs with long fingers and regular-sized all black eyes (no pupils). The creature appeared to be walking from right to left looking at the ground like it was looking for something. The creature was walking in the place where my dad's old barn used to be before it was taken down. There were small trees and old scrap metal and junk in that area when I saw the creature. I stared at the creature for about 15-20 seconds then I quickly closed the curtain, sat down on my couch and stared at the ground in shock/disbelief thinking to myself "what did I just see".(Unfortunately, I had no camcorders or cameras at that time) A few minutes later, I got the courage to look back out the window but the creature was gone. It affected me so badly that I'm paranoid to this day sleeping with a light on at night. I have nightmares about aliens and sometimes wake up screaming but sometimes i have good dreams about them where we make peace. There are also times when In my dreams I overcome my fear with anger and actually fight with the creatures using super strength and my body's internal chi. I recall one dream where woke up strapped to a surface with aliens all around me and I got so angry that I used my body's chi to explode out of the bonds and beat up the aliens. I am still angry with aliens for what they do to humanity (according to abduction reports).
