Weird dreams

I have been taking Fridays off. It seems that having a three day weekend is bad for my dreams. For the last few weeks, I have been having nightmares on the Monday morning (is it a sign that I don't actually want to go into work?). The other week, I dreamt I was being chased by dinosaurs. This morning, I had a dream I was stuck on scaffolding very high up from the ground and had to jump to the main building – but was too scared to do so. I'm not sure what happened to the pleasant flying dreams I used to have... other than the fact I don't seem to have them anymore ;-(
