If someone got murdered or went through a traumatic experience in a previous life somewhere is there any danger in returning there?

I'm guessing you believe in reincarnation. No reason, just a wild guess. But since that isn't what you asked... No, there's no danger in returning there. Because who the hell would ever know it's you in reincarnated form, that's why. Why would your previous-life-killer stick around there after killing you, and how would they possibly know you're the reincarnation of who they killed all those years ago? Seriously, your question has more what-ifs and just-becauses in it than a Hollywood reboot of a Hollywood reboot.
No-one has a past life - or a future life. That's all just silly superstition. Psychics aren't real either. Reacting to places may be believable, as I've felt it myself. Maybe if very strong emotions have been experienced there, the emotion can stay - like an echo or something. But it's nothing to be afraid of - it's just an echo from the past and your over-active imagination.
Lmfao are you serious? Past life? This is the only life you will ever have. Stop worrying about nonsense.
