Signs Of A Ghost

I thought that I should first let you know that I am very interested in the paranormal. I have always wanted to see and feel a ghost around me.

At my house I have had some really odd things going on and I want your opinions on if it's a ghost or not. I'll start off as to when I thought there might be a ghost in my house.

When I was around 5 I was on the computer and it was fairly warm in the room. Nothing felt too weird, but all of a sudden I felt cold air on my neck for no reason. My hair was covering my neck and I thought of how it really isn't that possible for only my neck to get cold.

When I was 7 I was in the family room I was watching television and I started whistling. Not long after, I started to hear someone whistling down in the basement because I could hear it through the vents. I kept whistling to see if it was just a one time thing, but for about three minutes it kept whistling with me. I got so freaked out I ran out of the room frantically.

As of this year I have had stranger occurrences.

I was walking down the hallway once and I can't remember if I had my iPod on or not but SOMETHING and I can almost remember it perfectly, said "hi" to me. I let it blow past though thinking it might just be my imagination.

Once I was walking in the basement, no one was home but in the far corner of the basement, someone sneezed. Can ghosts sneeze?

Even more recent, I had just bought a new iPod and I was playing with my photos I had put on it. I remember turning my iPod off to a certain photo and then when I came back it was on something completely different. I kept coming back to it and it was just not the same. I put up a sticky note saying "please don't touch iPod" and nothing has happened to it ever since.

I also remember that once when I was drawing in my room, I only caught it out of the corner of my eye, but something came flying at my head and then made a large thud on the ground. It freaked me out and I wouldn't go back in for another 20 minutes.

The last thing I can think of at the moment would be when it was night time. I was trying to get to sleep but had my eyes open because I couldn't. I noticed that a white shadow just swept through my room and then vanished. I thought that maybe it was the glare from my window of a truck or something going by but when I looked out the window I didn't see or hear and vehicle. Then again it could be explained by the moon shining on the tree and having some weird effect through the glass into my room. I did have curtains up though, so that would have been harder to prove.

I really don't know if these are any signs of a ghost but they are all true as to what I have experienced. I would love to hear your opinions on what you guys think it is and if by someway it is a ghost I would like some advice on how to contact it better. I really want to believe it is, but maybe it really is my imagination. I have never really felt cold presences and I really don't have that great physic abilities.
