When I was 7 I used to share a bedroom with my brother. One night, I have no idea what time it was, way into bedtime, I couldn't sleep. My brother was fast asleep and for some odd reason my eyes were drawn to the wall opposite to my bed. A luminous orb (for lack of better terminology) came in through the wall like it was passing through nothing. It slowly floated in mid air towards me. I can still see it vividly in my memory, and I'm sure I wasn't dreaming. The thing looked like a miniature sun, white and bright but somehow it didn't really illuminate the whole room and I could not feel any temperature change. For some time I was just fixated on it moving toward me but when It got very close I got scared and covered my face with the blanket not making a sound. When I finally decided to look back at it there was nothing.
Later on when I was older I had two other strange experiences which I can only describe as having been UFO sightings where the objects in question were aware of me looking at them but these happened outside and at a longer distance.
