Do you believe in ghosts?

Ghosts are not considered as scientifically rational existances, but they do exist, I suppose.


The day before yesterday, I stayed up and worked in the lab. I belong to till the sun rose. All the members but me already went home. At 25 O'clock, I had a short break and read some articles in Science in a dim room. Entering the room, I turn on the light, but half of the lights didn't work for some reason. Then I thought the half of the lights weren't lit because they were out of order. This WAS the mistake.

Finishing reading the magazine, I was outta the room and enter another room (a clean room), and do my experiments for about 6 hours. Just after that, it was almost 7 a.m. and I decided to go home, so I started to turn off the lights in the lab. Then I figured out the room I read a magazine was NOT dim. At first I didn't think it is odd, because I know some old lights are turned on in some moments. But I discovered THE HALF of them were NOT CONNECTED WITH THE SWITCH I turned on before. To put it other words, the room has two switches to light and I turned on the one of them, but the both switches were made on, though I was the only one who was in the lab..


This is not a fiction.

Don't you still believe in ghosts?
