Weird sounds at night

Hello all! I have been living in a living quarters trailer of friends of mine for the past year on and off. That said, it’s been a pretty good setup and everything (except for roaches last year). However, last night I was awoken to the sound of 4-5 footstep like things. Which is unusual. I’m not a heavy sleeper, so any sounds like that kind of freak me out, even though I live in the desert in Arizona. Where there’s tons of animals.

Anyway, I just went to shut off the lights a while ago tonight and again heard the same sounds. I don’t know if it could be mice or something, but it also sounded like it may be on top of the trailer itself. I’m just really freaked out about it to where I’m going to sleep with music playing.

Maybe I’m overreacting, but I don’t want critters around me at night. Have any of you guys dealt with this situation before? What do you think it is?

Thanks in advance for the feedback
