together we're heavy

i haven't had any of the "scary" dreams that i have heard people talk about when pregnant, but i have had very vivid and emotional dreams. last night i dreamt that i had to take the SAT again, and it was so difficult. i remember not knowing one answer! i also had to go get a bunch of school supplies and i was in a 5 mile long line (literally that's what it was in the dream) to buy stuff. i just felt this strange pressure of having to go back to school, and it wasn't like it was college or grad school, it was high school!
i had a dream the night before last that our friend's car was going to explode, so we put a brick on the gas pedal and shot the car through the front window of a house, and it went out the back window and landed in a pool, thus saving the car from exploding. another part of this dream involved us being in the same house and a girl i used to carpool with was there and on drugs and ashlee simpson and a friend came in with beer and i was worried that the people that lived there were going to be really mad at me for letting these drug-users/drunk people in the house (ashlee simpson?!?).
these aren't bad dreams, just high in stress. i wonder why it is that pregnant people have such vivid/emotional/bad dreams? does anyone know?
p.s. maternity clothes rule. comfortable, yet stylish now a days! :)
