Traditionally I believe 90% of spirits are just emotional implantations onto an object or area that is left over. So certain very emotional stress can leave a 'fingerprint' on something of the material world. So when someone got married and then the person who got married has a ghost of themselves at the same place, even though they are not dead.
9% of the spirits are other kinds of spirits such as demons, angels, fay, different spiritual creatures, etc...
The last 1% are the deceaseds actual spirits that linger here. I haven't worked out how the soul and spirit interacts but my theory suggests that the soul never stays in this realm and most of the time the spirit of someone moves on. Now, if that means the spirit is reincarnated or what I don't know. The soul is more of the individualistic moral person that formed throughout the living life, which the spirit is the life essence itself and has a wider connection to all other living and non living things.
Anywho, that basically explains what I think about that part.
The main point of this discussion is something that bothers me from time to time. My mother told me a few times that when I am around her that she can feel my father with me. When I go away he goes with me. She says that he is attached to me to guide me. Now I know some of the deceased does in fact become spirit guides for the living. Now I can at times feel him as well and it makes me sad because I did have a deep connection with him. I just want to know if this is true, how do I go about finding out it is, and why is it this way? I know my mom has seen him in her dreams from time to time, but how come I can't?
