I'm a believer of the paranormal because of my personal experiences growing up. My family and in every single house/apartment that we've been too, there's always been some sort of activity, and spikes in activity sometimes happened whenever we were close to moving to another place.

This one isn't mines personally, but my parents:

A few weeks before we moved to our current house we were staying at an apartment. It was night time and my mom was already asleep, but my dad was just lying down on the bed. He said he could feel something between him and my mom, but he couldn't see anything. But he heard it run from the bed to the front of their closet where it would then start running in place. On the second night, it was between them again, but this time both my parents were awake. You know how you can very clearly tell when someone is crawling on the bed? From what I remember my dad telling me, it quickly crawled out of the bed, ran to the same spot in front of the closet, and starting running in place, then it would crawl back into the bed, crawl out, and run back to the closet area. After that, it was gone.

I think my parents have become desensitized to these types of things, more so my dad than my mom. I have a huge collection of personal stories. I love whipping them out whenever me and my friends have sleepovers.
