I don't remember a great deal of detail of this dream, but I'm pretty sure that my little brother and his friends had accidentally killed someone, and I helped them dispose of the body. They were panicking, but I helped them cut the body up into pieces and put it in air tight containers, inside plastic bags, and I'm pretty sure I hid it in Cambridge Science Park.

The other part of my dream that I remember is talking to them and saying "If I have to move out of my house I will buy my own house in Maidenhead." I don't remember the context of this at all.
