I do believe in ghosts.
We have to remember that the human senses are very limited.
The eyes can only detect that which is in visable light within visable light within 3rd density. Yet, visable light it not the only frequency that exists on 3rd density.
Other animals are able to see in infared, light just outside of the human visual range.
Infact, inorder to detect most of the frequencies within this density, we need the aid of a machine.
Atoms are not solid. We vibrate with other objects and people in the same frequency with us. This is why we cannot pass through walls, tables, and eachother.
I think that death is not an actual death as we have been taught but a change into a different frequency.
I see the body as a biological computer.
When there are errors within a program in a computer, that program does not function well or at all. If there is an error in the human body, we call this a disease. There is an error in the DNA, or an error with the lines in the programming.
When we turn a computer off it has no energy and is thus not working. It is cold and dead. As is the same with the human body after death. If any of you have witnessed a loved one which has passed on, you note that they look dead, lifeless in other words...there is no energy within the shell or body computer.
So merely instead of death, it is a change in frequency that which the humans in their body computers cannot see due to the limited range of detection.
Sometimes when energies are high or sometimes momentairly out frequencies may become one or the entitiy may have had enough energy to bring his/her/itself into visual range within our frequency.
