I don't believe in "ghosts" but...I leave room in the universe for "leftover energy" which could explain oddities.

The moment I first walked into my exes house I felt something strange and stated "hm, I think you have a ghost here" he replied by saying "how did you know?". Later on he told me that weird things have always happened to him since he was a kid that he couldn't explain. Things that a parent might say was just a bad dream.

Right before this discussion, I had used his bathroom and my eye caught the attention of a jar on his cabinet, the top of it was uniquely shaped (used to store q-tips or something) so I made a small mental note of it being interesting. Left the bathroom and we had that conversation mentioned above maybe an hour later.

Back to that conversation. We were exchanging stories when we hear shattering glass. We both look at each other like "Wtf..." but when we realized it came from the bathroom I just knew what it was (because it was the only glass item I saw). We go in and sure enough, it was the lid of the glass jar.

I told him I know he won't believe me, but proceed to explain that it was impossible for the jar to fall over because it was so far back in the cabinet, plus when I used the bathroom it was the one thing I made a conscious note of in my mind. We both proceed to freak out but believe each other.

I know I'm embarassing myself by saying this on reddit, but, it happened, including other small weird moments that lead me to believe there is more out there than we know.
