You then say "So something has to be re-awakened, in the present state". Then I ask, what do you think it is!?
The key question is what is "being born" into this dimension really is? Since everyone needs to sleep everyday and since the wave patterns while one is a sleep are significantly different from the ones when one is awake, it makes it obvious, at least to me, that the soul doesn't even exist in this dimension.
So, being born into this dimension is an illusion for the soul. What it thinks is real when it is "awake" is ONLY a projection..
This is very much evident specially when someone didn't have enough sleep. At that stage, even when they are "awake", they are in a very confused state of mind in terms of where they really are and what is really real around them! In other words, they are lost between dimensions..
Significant jet lag does similar things to the mind...
