Well, I don't know if this was really a dream or if I was just half asleep, but the night before I cut myself and put the blade, together with a knife, on the floor next to my bed. I was strangely distressed in my dream, although I never tend to do things like that, which cause great pain, to cut my wrist arteries and finish it as soon as possible. Probably the pressure was only so great at that time, which is why I thought or dreamt about it, but this thought vanished quickly.
With the knowledge at the present time I am actually happy that I didn't do it because it wouldn't have helped me much anyway. The bleeding would have taken too much time and just one cut on one wrist would not have killed me, I guess.
