What does it mean to have a dream where your boyfriend wears diapers? Lol?

In my dream last night, I was at this place with my boyfriend and he eventually was like "I'll be right back baby, I need to change diapers." I was like "Whaaaa???" He was 18, in the dream like he is in real life and he still looked the same. Anyways it was so weird though lol. What does it mean? :P
