Bats will not attack humans and would not bite you unless you grab them and try to hurt or hold onto them and they are frightened. You will always know if one is in your house because they fly around where you can see them and make a swishing noise and sometimes a high pitched squeaking. You do NOT have to see a doctor if there is a bat in the house unless you have touched or handled it (because some bats can be sick with rabies which is dangerous for people).
The pinpoint dots on your skin could be from anything from a tiny bug bite to a tiny patch of psoriasis (a skin condition that often starts with a tiny scab). If they are not bleeding, itchy, hot, red or swollen they are nothing to worry about. I think you are letting your imagination get carried away.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
