You probably were having dreams about something $5000 and probably that Jacque guy. Then you "slept walk", but instead you slept texted. That'd be my guess. And I'm guessing the drugs have something to do with it.
If you were awake and txting, would you actually txt "5000$" or "$5000"? I'm not trying to correct you... just wondering if it was consistent with your waking state. Ed O.
It's happened quite a few times to me before. Except it was waking up, talking to someone, sleeping for a few hours, and then completely forgetting the convo even occurred. Also, I have issues with turning my alarm off subconsciously, in half-awake stupors. Usually happens whenever I'm too sleep deprived. An easy solution for me is setting multiple alarms to wake up, and then doing a puzzle or some math questions (hey, don't judge!) right after I wake up just to get completely conscious.
"Tonight", as I generally do, I'm putting my phone across the room so that when the alarm goes off, I have to get up to turn it off. In the case of the sleep-texting, the phone was right next to my bed.
