A Memory before born

I heard recently very mysterious story that a newly born baby sometimes has its memory when it was inside the mother's womb.Believe or not,there're many evidence that a baby experienced floating in the air just above its parents expecting to descend and materialize itself to be a baby.Though there is a little difference of what they say like one says it had wing of its back to fly or another one was looking for parents who seem warmhearted,there is no doubt that they've already been conscious of our world.Our world is full of mystery.
