Crazy Dreams

I have a 15 month old daughter and a 5 month old son and for the last few weeks i keep having dreams that im pregnant again every night. Im not trying to get pregnant, in fact i have the copper (10y) IUD. Its just weird because i had a dream that i was pregnant before finding out that i was pregnant with both my kids. I do want a 3rd baby but not for 3-5 years. Anyway, im rambling a bit but im just wondering if anyone is experiencing anything similar? Or am i the only one with these crazy pregnancy dreams?
