A question about past lives?

Now this is kinda an odd stretch as to how I got to needing this answer. So a few months ago I went to this house with my friend. It has the worst vibe to it. Just basically oozes evil. Well a darkness, evil sounds a bit harsh. Anyways after that something followed me home that night. It's dark, strong, and intimidating. He scares my friend but not me. Not really. I can feel him and he's strong but he doesn't scare me. Which I think he should. After that night I've been drawn to that house. But I've always had a part of me drawn to darkness. I know I'm not dark or evil or whatever you want to call it. I've just always been . . . brave when it has come to testing the waters with that sort of stuff (Ouija, invoking spirits, just messing with things I shouldn't). It doesn't scare me but it also doesn't feel like it can hurt me even though it's a powerful darkness. I feel like my interest and my protection concerns someone I was in a past life. If that makes sense. And I wanna talk to someone who can actually help me figure that out. Who I was. Not just some psychic but a person who is specific to past lives.
