Seeing A rainbow in my house

I know this sounds crazy but I really saw a rainbow in my room. After showering I have a small little closet room that’s side by side to my bathroom & that room just has a bulb in the ceiling. This day was a pretty rough day. My phone broke, had a big argument with my S.O & when I got out of the shower and went to grab my clothes there was a rainbow under the light bulb. The rainbow looked like it was smiling at me & VERY colorful... if my phone wasn’t broken that day you could’ve seen it clear as day in a picture... crazy thing is I haven’t seen it since... idc if this sounds like a bunch of bs I just truly want to know if anyone else has had this happened to anyone else?!🤯🌈
