does the dead still come back

I am an African and i belief spirit leaves on after dead most especially that of our parents because they are the bases of our being.death means someone who was available to you is now absent.The closeness you had with someone when they where alive,when they die it’s either something falls from your hand and breaks or some strange feeling just get into you.The human body has three dimensions which are the physical,mental and energy body and physical existence.The other is spiritual not seen physically but relates or connects with the physical in other words a transits stage or state.When someone dies we say they are no more that’s not true because they are still much in existence.The physical body is borrowed from the earth isn’t it?is just a piece of earth noby is allowed to carry any earthly thing to the world beyond so even the body is earthly.The spirit finds another body after dead which it reincarnate into but if it doesn’t it roams the world in the form of ghost until it finds a body and the more it roams and gets intense it can then become physical.There a lot of them around us.Some people feel their presence most times with a their spirituality.These mostly occur when a person died untimely especially by accidents,suicides,murder or another way.When a person dies at the appointed time like old age he may find another body within hours.This is the best way of dead because your spirit would not be roaming the world for days,weeks to years.
