What lives in my ceiling?

So, I’m pretty sure that some creatures live in my ceiling or perhaps on my roof. Every night before I go to sleep I hear an intermittent pitta padda pitta padda pitta padda above my head. The first few nights I heard this I freaked out. The headlamp was definitely one of the best things I brought. I hang it on my bedpost and whenever I hear a strange sound or need to go to the bathroom at night, I wear it. I guess the creatures in the ceiling can’t hurt me, so I will ignore them for now. I like to think that they are cute little geckos or pigeons perhaps. I try not to think about the fact that they might be rats or cochroaches.
