Well, this is a difficult one! And I would suggest here that it varies very much according to how much knowledge the spirit had when it came here from the spirit world in the first place.
Some spirits or souls are far more evolved than others, regardless of their material life. It may well be that a person may seem to be well developed psychically and more so than, say their partner. But, in their spiritual home it might have been the other way around.
We have no memory of our spiritual life whilst on the material plane, as it would prevent us from getting on with our purpose. Therefore it is hard to tell how evolved each of us is.
If a spirit is well evolved, it may be an almost instant event for them to go home after they pass. They may see their loved ones waiting to greet them and accompany them over to the other side, making their transition relatively easy.
For a less evolved spirit it may take a bit longer, but they will still have loved ones waiting to greet them and go with them to the light.
Sometimes whilst on their ‘deathbed’, a person may talk to an ‘invisible’ being and appear to be watching someone, usually at the end of their bed or at least in the room. They will mention loved ones names and surprise the relatives who are at the bedside.
It is often thought that it is drugs which cause a dying person to act in this manner, but it is really their ‘dead’ loved ones come to take them back home. They can really see them even if you cannot.
Most of us find it rather comforting that their loved one will not take their ‘final’journey alone.
