ANSWER PART 2:
In this I agree with the soul of the late Abraham: even the ghosts spoke, if the dead returned, if the creator of the universe himself made his voice heard in a world inhabited by 1 billion materialistic people lost in skepticism, I think the most would ignore, turn away, plug their ears, or make exclamations like "am I dreaming? Do I have tricks?" ascertained that they do not have the trivia, then everyone would start overwhelming the spiritual entities with questions or would expect them to solve all the problems that one has in earthly life with a snap of their fingers, or worse still they would do idiots with them. (on this the human race is an undisputed champion).
in short, I think the question is that perhaps the attempt to communicate is there, but it is not perceived in the least due to the mental attitude that one has in earthly life. or, even if it were perceived it would be dismissed as a coincidence, or a strange dream, or a deja vu, or a "I'm too tired I worked too much" or "I'm hallucinating". About the fact that someone into the life, mostly folks are not happy cause living a live when is forced to do some artificial fate and job instead and the desire of the souls, well, souls are not perfect and maybe
even their judgment is often wrong. (at least by mortal point of view)
like I remember in my prenatal memory that I said to the voice I was talking with (unfortunately I don't remember who I was talking to), that "I wanted a quiet life in which to have fun with games", and I was satisfied only for the first 14 years of my existence. apart from the fact that at the age of seven I had to have eye surgery for glaucoma and go as far as Spain to do it because that type of surgery in Italy was experimental and too risky.
at the first opposition of saturn the troubles started for two years of hepatitis that forced me to abandon school, and, even now, I have a retired life with my parents, in which I spend my days mainly on the computer to study, play, chat with people, reading forums, studying, writing.
not exactly the concept of "tranquility" that I asked because I go from one casino to another.
I can tell you that there is the free will, the lack of awareness, and also the fact that you live in a hard, terrible and selfish world in which everyone thinks only of himself and does not give nothing about his neighbor, or in which people are just too focused on earthly things. most people don't even ask the question "who am I really" "what am I doing here" so what do you expect ... about the fact that 99% of the time people don't remember their pre-existence, well ...
suppose a person in a previous life was raped, or killed or committed violence or harmed others. what advantage would it have in remembering this? to be plagued with guilt for crimes committed a lifetime ago? would end up going crazy! not to mention the risk of incurring schizophrenia, if you completely remember your previous identities, name, surname, profession etc. now, for a newly born child it is already quite difficult to manage, but think for an adult who remembers everything clearly in a regressive hypnosis. could he amalgamate his me and his current identity with the old one? or would he go mad or would he have personality disorder of some kind?
this is just my personal opinion, but I see it like this: earthly life is simply a place to learn, a test bed, a place full of challenges and pitfalls, challenges and pitfalls serve to grow and mature. there would be no growth and understanding if there were no difficulties and pain. there would be no search for improvement if there were no falls and if it were all perfect and bucolic.
everyone, at birth, has in some ways, a script and a part to be played in the grand scheme of the universe. and this script serves above all to his growth as a spirit and to help other souls, for good or not, even for the most stupid and insignificant gestures, such as repairing a tap or shopping. each time he returns to earth, the soul actor receives a different script, a different scenario, and a different part to play. now the actor - soul is always the same, but the script varies from life to life. a bit like orlando bloom, who in the pirates of the caribbean plays will turner while in the lord of the rings he plays legolas. he could therefore say that legolas is the "reincarnation" of will turner, if you know what I mean. same soul, different roles. but deep down it is always the same entity.

now let's take a random actor and put him in front of all his filmography and all the revelations of him interpreated in various films. we analyze common patterns and characters with redundant behaviors. we try to glimpse a pattern, perhaps this way we can understand why we come to earth over and over again to play different roles in different parts. which is the least common denomination among all the existences of a person?
most funny: if we look the things by the point of view of will turner or legolas... "legolas, my dearest elf friend! into another life you was a heroic youngman that fought with pirates, son of pirates."
legolas "what??! seriously? probably you are joking! how can a elf been a human?"
obvious, legolas can't understand this. but the actor, orlando bloom, sure know, and know they are just characters he plays in movies.
so, what's the drama of human condition? the fact that peoples is trapped into theyr characters, so they can't feel the actor inside.
