This is the weirdest thing thats happened to me, about 10 months ago id say. It was pretty late at night , and I was in my room, with my ipod on not too loud, and i was texting back and forth. My brother was in his room next to mine (we live in the basement, with seperate bedrooms next to eachother, and living room on the outside), and my younger brother has his room upstair with my folks, and from time to time, he comes down to hang out with me. And this one night I was texting away listening to my ipod, when I heard a knocking on my door, I thought it was my younger brother, it was about 4 knocks, so I said "come in", but no one entered, I opened the door and steped out, to take a look around, but there was no one there, pitch black, I was like WTF, and first thought was outloud i said " Oh shit, that was weird". Creeped me out, but then i was like "Oh it was probly my brother next door", so I asked him, and he said he didnt knock on my door, but that he heard the knocking too. Then we talked about it, and said he also thought it was Benny(my younger brother), but he didnt hear the footsteps we usually hear when people come downstairs., neither did I, went upstairs and turns out it wasnt Benny cuz everybody upstairs was sleeping, mom, dad, younger brother. So who knocked on my door that night?
