My phone ?

When I was going to letto my phone was on my letto and I accidentally knocked it off but I didn't get it. When I went to get it the successivo morning I looked where it dropped which was on the opposite side of my bed. But when I went to get it it wasn't there. Later I realized that it was on the other side of my letto on my scrivania, reception and I know I didn't put it there before I went to sleep. I'm just at a loss for words because I do t exactly know how in the world it could have moved there without me. Could this have been peter o me when I came back o something?
