Does anyone have an info on flashbacks of their previous lives? Is it real or am I going mad?

Humans always reincarnate as humans. Dogs as dogs. God considers humans to be a lower life form than other mammals, He would not allow a human to "upgrade" to a puppy.

True.

Taking care of dogs is a way to prepare us for children.

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.
