A few times I have fallen asleep with my phone in my hand and next morning found a message from a seller on facebook marketplace asking when I wanted to pick up the item I've messaged them about.
Went for a piss and got into bed with the mother in law...made worse as I was stark bollock naked...made even worse as apparently (i.e. according to the mother in law) I climbed into bed in a "top and tail" styleee. My wife woke up the next morning - surprised I wasn`t in our bed - looked for me and found her mum cold and under a tiny blanket she found in the kids play room who told her to tale before I was even awake... Mother in law stopped the next night too and barricaded the door to her room with a bedside table just to be safe...
While I'm falling to sleep I sometime get a feeling like an electrical shock going through my head. It's known as brain zaps.
I sometimes wake with a jump/shudder but no electrical shock through my brain - but then, I am notoriously lacking in that department
