Am I overthinking

All of a sudden I started waking up around 2-3 in the morning every night, I didn’t get a goodnight sleep & my anxiety was bad that i would start crying. I would think my bed was uncomfortable so I started sleeping in my sisters room & I was able to sleep through the night. I slept over there for like 2-3 weeks. I got my parents to switch our beds so now I’m back in my room since 2 nights ago & in those 2 nights I kept waking up in the middle of the night again although I feel sleepy & my anxiety is starting to get bad again. Could there be something in my room or is it just in my head?
