I woke up once days ago, with my toe falling asleep on me and it felt like frost bite, very bad too. But i am inside not outside sleeping, it hurt too much to flex it. This ruined my dream that i was having and i was getting annoyed about it and woke up and cursed my toe for distracting me, odd thing is, it had nothing to do with my dream lol. I got up and it went away in 5 minutes.
