I'm in desperate need of some reassurance here, this morning I woke up at about 4am soaking wet around my bum. Thought I must've come onto my period (expecting it) but no. Bed soaked, so I laid a towel down and tried to go back to sleep. Soaked through really quickly. Based on the fact that the mattress was so saturated and the stain on my sheet this morning, I can only draw the conclusion that I peed myself in my sleep. I've never heard of adults doing this and just wonder if it's ever happened to anyone else? Worried about going to bed tonight!!!
