Dreaming about Dick

Another weird dream last night which I thought I would foist upon you. I was on my way back to England in a plane. Suddenly, the next thing I know I am walking around London in the middle of the day. It's about a day and a half since I was on the plane, but I have absolutely no recollection of anything that has happened in between -- it's as if there was no gap at all. Checking my wallet, I find that there is a ticket for a left-luggage locker in Victoria.

Now, clearly this isn't a proper dream; rather, it's quite patently the start of a Philip K Dick novel. I just wonder if his estate can sue me for dreaming something so derivative?
