Do you ever wonder why we can create all these things that dont exist? What i mean by that is it does exist or is real on some level of our consciousness either by dynamics or metaphor. Creation comes in many forms, doesn't it? Why do we have this constant need to create and purge? Nature is always creating in one form or another. For good or ill.
Take, for instance, dracula by bram stoker. How in the heck could anyone think of such a mythic being? There are no undead people who suck the blood of the living. but hold on. There are people who predate on others and its not always literal or obvious. There are those who are toxic or draining who feed off the energy of others. The modern term is psychic vampirism. Do you know there are people who do this to get extra energy to even help them become successful at anothers expense? All is not as it seems in the world. The transactions taking place are not all in visible form such as cash.
What makes people think we cant or even unconsciously create ghosts? That we cant project our thoughts and feelings to create living entities? We know by experience that we not only affect others by thought but also energetically. Havent you ever detected 'vibes' around people and surroundings? What makes people think its impossible that at times it may be extremely strong and we emit thoughts positive or negative so strongly, it can act as a force or shadow. A living entity or refuse of ourselves from the darkest, vilest, evil aspects that would be termed demons to the light, good or higher consciousness we would term angels. Sometimes we get to see all that is hidden inside of our multilayered beings and surroundings with the masks we wear or surface identity as we go about our daily lives. Sometimes pieces of us break off and get absorbed by the environment or vice versa. Sometimes another can steal a piece of your soul or its given. Its energy. We are giving off things constantly to our environment as much as we absorb and are affected by it, much of it unseen. Sometimes we may see it in literal symbolic form.
We dont just act on a literal level and only affected on that level. There is more going on that we call reality beyond that is visible. Sometimes, it becomes visible.
I think ghosts can be due to several reasons. It could be people who have passed, beings from another dimension and also just a chip off the old block. A segment or piece of life force broken off from a living being. What shape it takes and its nature would have a lot to do with who it came from. Demon, angel or just benign. It comes from us. We are its creator. Our shadow selves, for better or worse.
