I worked at my undergraduate University in cloning research, and my friend Adam and I really wanted to clone this one other professor. We heard a rumour that he had collected his sperm into a baby bottle and buried it somewhere on the University grounds, 20 years earlier, but everyone was afraid to ask him about it. We used some occult ouija-board technique to discover where it was buried (under a bush in front of the student union) and dug it up. It was still warm. Before we could do our genetic research, we had to test the sperm sample at a dinner party, by hiding it amongst the food. Not in a disgusting way where people would eat it, but we had to put the baby bottle on the table, and strangely no one could see it even though they were looking right at it.
In the second part of the dream I was in the room my mother uses for her sewing work and I somehow knew that there was a door in the ceiling that had been plastered over.
