I think we mostly heal on the other side, before we are born again. There seems to be some lingering trauma that can result in phobias. I'm afraid of water, because I once drowned. It seems to be mostly the immediate past life that causes problems. Knowing why you have the fear sometimes helps. I think that's one of the benefits of regression, but I know you have had one. Maybe you should try visiting that life again, and see if there's anything you missed.
I think it's not my own death. I was just wondering about death in general. I'm afraid of vulnerability in relationships because I hate to lose the only people who were close to the real me...I don't think that's from a past life, but it could be. Who knows? I am not sure I have the patience to do another meditation but I'll try and see what happens.
Edit: I tried but I don't think I'm able to do it again, and I don't really care enough
