I know for a fact that we forgot about remembering Home to which we long to return which is both within and without , beyond space and time.
our suffering in this life comes from our separation from Home, or as a mystic used to say :
"Live in this world as if you had never set foot in here before, and in the next as if you had never left it."
But ,that was not what you were looking for , i guess.Cheers.
These aren't parasychological studies or specifically about pre-birth memories, but they are books related in some way (such as alleged communication between parents and unborn children) to pre-birth existence.

A limited number of accounts of near-death visions that include unborn children suggest a life before birth. The unborn children in these visions have been described as spirits, as children or children but full-grown, and as residing in another world, perhaps different from the realm of the afterlife. The arrival of these children into our earthly world is similar to the departure of near-death experiencers into the other world.
