My brother and I were renting an old house in Longview, WA. This house was apparently built back in the 1920's. My room was in the basement. Well, it basically WAS the basement. All the lights and electrical plugins were on the same circuit controlled from upstairs. Rather than going upstairs to turn the lights out when going to bed, then stumbling down the stairs afterword, I would just unscrew the light bulb above my bed. This way I could leave my computer on and still have an alarm clock.
One night, I unscrewed the light bulb just like every other night. I went to bed and quickly fell asleep. At about 5am, I awoke to a flashing light in my room. I opened my eyes and saw the light bulb which I had unscrewed was turning on and off very fast. I figured someone must be playing with the light switch upstairs but I looked at my computer, and it was on. If someone had been playing with a switch, the computer would have been affected. I laid in bed for several minutes watching the light flick on and off. I didn't feel afraid at all, in fact the only reason I hadn't got up is I was hoping it would stop without me having to get up. Lazy I guess!
Finally, after a period of about 4 or 5 minutes, I got out of bed. As soon as I was standing, the light stopped turning off and on, and just went to fully ON. The light bulb had completely screwed itself back in.
I tried to pass it off as electrical problems, until I remembered what my brother's old roommate had told me before I moved in. He had said that one night he had woke up and saw a shadowy figure standing over him. At this point, I was too awake to sleep any longer so I got up. I went upstairs and watched a movie. When my brother got up, I told him about the light show. He told me that everyone that had lived down in the basement except for him had had an experience of some sort. Some just had gut feelings, others like me had seen something unexplainable.
I talked to several friends about it and ended up talking to my girlfriend's mom (of all people) about it. I was in the middle of my story when her friend came over (who was supposedly psychic). I had met this woman once before, and barely knew her name. She knew very little of me, too. She asked what my girlfriend's mom and I were talking about. My girlfriend's mom told her I had had a light show. She stared at me for several seconds and got visibly upset. She said somewhat franticly, "It's trying to tell you you're going to have a bad accident..."
She looked at my girlfriend and said, "Does he drive fast?" To which my girlfriend replied, "Yeah, kind of..."
She got more upset and said, "You need to slow down! It's trying to tell you you're going to have a bad accident!" She paused for a second while staring at me some more, then said, "But you won't get hurt. Someone else will..."
I didn't know what to believe. I wanted to think the woman was a quack, but then... How did she know I drive fast? Even my girlfriend's mom didn't know my driving habits. I thought about this for some time, and decided to take things a little more carefully for awhile.
A couple weeks later, a spring pack came apart on the rear axle of my lifted jeep wrangler. The center pin had snapped and some of the leaf springs actually came out on the road! Just a tiny piece of the center pin kept the axle for flipping around and causing an accident. If I hadn't been taking things easy, bad things could certainly have happened.
Ever since I moved into this place, I would hear footsteps upstairs when no one else was home. This happened to be a duplex, so I would just pass it off as being the neighbors somehow. But after this experience, I paid more attention to the footsteps and determined they don't come from the neighbors' side of the house. They come from directly above me. All the other people that had lived there have heard these footsteps.
