Is it a ghost?? I need help!!!

as long as i can remember i have been able to feel spirits and they come to me through dreams but until 2 years ago i had never seen one on camera....
my niece was playing with my camera and captured what looks like a spirit in 3 different places in my bedroom. now take into account that these were taken at midnight so there was no light outside and the only light on in the whole house is the room we were in. i tried to recreate the cloud that you see by putting fingerprints on the lens and shaking the camera while taking the pictures and they came out clear so i have already ruled out the possibility of a camera flaw. also my father passed at 11:58 pm on march 8th 2008 one year before these pictures were taken. the pictures can be seen on myspace.com/nikkijg26

It is a spirit, he's trying to manifest himself to communicate, but unfortunately, he's too weak (in the form of energy). Your mind, which is your conciousness and personality, and created through energy, which science has ruled out that your brain can develop enough electricity to power a 30-watt light bulb. The only way me and you can do what we do, is through this energy. However, that energy is released once you enter the spirtual realm because your body no longer produces it. Heat is made up of complete energy. When you feel 'cold' spots, that's your father trying to suck the energy out of the heat in the air to use as energy to manifest himself, but sadly, he's too weak. One day, I esure you, one day, he'll grow strong and manifest and evetually you'll have contact to him once more. Don't be alarmed, i esure you, he's not trying to scare you in any way possible, that's the last thing he's trying to do, he's just alone in the spirtual world and has no one else but himself. He can see you but, you can't see him, only in apperisions that seem to be a blur.

No, there are no ghosts or spirits. You niece took the photos while holding something a short distance in front of the lens.
