A friend was texting me about how depressed she was. I told her to call if she needed me and I could be there in fifteen minutes. An hour later, I noticed 1) my ringer was off and 2) I had a missed call from her. Cue a half hour of calling, texting and panicking with no response. So I went over.
Turns out she ass dialed me in her sleep. Luckily she thought it was sweet rather than weird.
This is the risk when 99% of your social circle is made up of psychiatric patients. It could be an ass dial or a suicide attempt and you never know which.
