Mysterious Haunting In My House

Before I start my story I just want to say, I am a very big sceptic and am not one the usually "believe." Contradictory to this, my life has been full of strange and unexplainable experiences. Every time something like this happens, I look for any possible way for it to be scientifically explained. Some of these occurrences leave me dumbfounded and I would like to understand them better. I do believe in the afterlife and am interested in understanding the unexplainable.

This first story occurred when I had just turned 9, in my house. My house is larger than most, but not huge. Most of these strange happenings occurred with my friend who is very similar to me and we both share our experiences as, even when separated, our stories seem connected.

On this day my friend was over at my house and we where playing some spy game because I had just received a motion sensor toy that uses a laser point, and when broken, sounds an alarm. Well our "base" was in my attic, and outside of it we put the laser outside to keep out "intruders." The attic always had a weird vibe but we ignored it.

Well, we were downstairs eating lunch and forgot we had left it on. Then all of a sudden, we herd the alarm sound so naturally I thought it was my cat. But when we came outside of the kitchen we found my cat napping on my bed.

Now after doing research on my house, I found it used to be an olden doctor's office. And on top of this, the room that was our "base" (which was the guest room) had a patient bed in it that had been left in there from every previous owner.

At first I thought I must have been a faulty battery, but even after changing the batteries, it continued to go off. When we put it downstairs though, it didn't go off. We checked all over for any mice or rodents, but there were none to be found. Even when we were staring right at it, not in the line of the lazier, it would go of, but nothing seeming to trigger it.

Now at this point we started to get scared so we ran down to my room and slammed the door. We started to hear footsteps walking down the hall, but when we looked under the door, there was nothing there. I have a bunk bed and the bottom can be a bed or a sofa. I do not share a room.

At this point we are scared stiff on the top of the bed and then all of a sudden it stopped and the air seemed to lift and we were no longer scared. But this event sparked the beginning of many paranormal events throughout my life and I will be posting about those separately.
