Asaalamualaikum warahmatullahi wabarakatuhu.
I dream, that I was in something like a theater or something on my own with what felt like was a child sitting behind me. I then came out and looked at my feet, I no longer was wearing my own shoes but I was instead wearing childrens slippers, and each slipper was a different colour.
Please interpret for me. Jazakallahu, khair
Since you are in a theater, it means you are involved in matters which are distracting from things which really matter. It means that you maybe wasting your time with childish matters that are taking you away from your duties to Allah, or to your family. That is why you are wearing children shoes.
