Other 'worlds' with other 'rules' or existions. Life here or on other places and so on. Well, it is a bitt about what oneself at the moment se as ones 'truth' and dosent mean one is wrong or right, right:)
If you don't feel like 'from this place' that 'something isn't quite right. You probaly arn't of this world originally, maybe also it's ones first life here. And haven't goten used to the 'rules' and so on.
Some are 'new born souls' and having theyr first 'life'
Those mostly don't belive in past life and so on, sins they haven't had anny:)
And so on.
Some things that are mostly related about past life.
When one feel a conection with some that are, well. Deja vu ish. Like you alreddy know them. You probaly do.
If you feel conected to any special 'mytholigy/belife or mythology being.
Could be that you have encountered these on the 'place/world' where they origin from.
(example: dragons, werewolf or the half man half 'dogs' in Egypt. And so on. Difrent cultures with almost identical descriptions of the beings. And great distance. )
And so on and so on:)
