How do you explain this happening?

One night I was asleep, I woke up because of a bad dream. I reached up to turn the lamp on like I always do. The lamp wasn't there. So I turn on the overhead light & my lamp was taken apart & placed neatly on the floor next to the nightstand. The lamp shade is the kind that has 2 screws that are connected by the lightbulb which is not easy to emble. Then the lightbulb was placed next to the shade on the floor. The lamp itself was in a standing position next to the lightbulb & shade. Now on my nightstand there are things I alway keep on the table in front of the lamp, well nothing was moved. If the lamp had fallen, I would as least heard it fall,or the stuff on the table would've been knocked off the table. Right? So what is that, very strange & creepy? E-mail me ritamagdin@yahoo.com
