Many people have experienced waking up from a dream of going to the bathroom to find that they've either gone, are going, or really have to go. For most, this is a one-time occurrence and it's nothing to worry about. If this is a repeated problem, however, you should seek help. It's not the dream that's causing the accident, it's the fact your body isn't waking up to its need to urinate. I was walking upstairs and felt my nightgown against my body. I was warm, surprisingly so for wintertime.
I awoke on a Saturday morning to the same dream I always have. I would go up to my mommy with my thumb in my mouth while she's sitting with my aunt who is changing my cousins wet pull up from the night before. I would watch as she slowly rips the princess pull-ups sides off and takes a wet wipe and wipe the remaining pee off her. I see my cousin giggle as she apply's cream on her and says I'm putting a diaper on you for the rest of the day until you can learn that your not a baby any more. I look at my mommy and say I want to wear one too. She smiles and says only babies wear those so if you show me your a baby then I will have to treat you like one.
