Stabbing Yu Lee
I don't remember the details of this dream (as I just remembered it from a while ago), but me and Yu Lee were in a situation where we were hiding from 2 other people that were trying to kill us. We attacked them several times, but every time we defeated them they would come back.
Somehow, and I don't really understand the logic here, I realised that this would go on forever unless everyone died apart from me. Yu Lee was getting more and more distressed, and I came to the conclusion that it would be kinder to put her out of her misery than to continue fighting.
We were at my childhood home in York Avenue, Slough, and I grabbed a kitchen knife from the kitchen and told her to go to the workshop at the bottom of the garden. Once we got there I stabbed her to death, first in the stomach and then in the chest. This was extremely distressing and caused me to wake up.
It took me a little while to fall asleep again afterwards.
