Alright, these stories are true, I swear it on my life.
I used to have this room with a sliding door, before my house got remodeled. One night, I woke up at around one-ish for no reason at all only to see my sliding door slowly slide open several inches. Now normally, this would have been enough to freak a little kid out (I was around seven at the time), but my cat knows how to hook his paw around sliding doors and open them. I thought it was him coming in to leap onto my bed or something, but no cat came in. I kept staring at the door, waiting, when a light flicked on outside my room, then turned off again in about a minute. I screamed for my parents, and they came and searched the entire house for possible intruders. There was no-one there besides us. This has not happened since.
Another time, this time in my new bedroom (this one doesn't have a sliding door), I woke up again in the middle of the night. I was staring out my door, because that's the way my bed faces, when I saw something hanging on my door frame. I could have sworn that it was the exact shape of a gargoyle with bat wings. It had no eyes, no details; it was just a shape that was darker than the other shadows outside my door. I stared at it and blinked a couple times, but it did not go away. I pulled the covers over my head and went back to sleep. In the morning I looked, and there was nothing that could have made that shadow that was in view of my bed. I now don't look out my door at night.
Once, right before I went to bed, I heard a boy my age say my name quietly. I did not just hear it in my head, I heard it with my ears too. The voice comforted me, and I fell asleep feeling safe.
I have no logical explanation for these stories. Do you?
EDIT: I just read over others posts about there being increased activity this summer. I haven't noticed any as of yet (excuse me while I knock on my wooden desk), but I must admit that the weather where I live has been quite strange, rather cold and gloomy. Also, I have experienced several days where, at a certain time (usually about three in the afternoon) the world has looked a bit surreal, like a large transparent screen has been put over it and you can only see it if you look at it side-long.
