Pregnancy nightmares!!! HELP!!!

Does anyone else have pregnancy dreams and nightmares??? I am 17 weeks pregnant and have had nightmares and weird dreams the last few weeks. Does anyone know of any ways to help with this? Any dr. Recommendations for medication, sleep aids, or tips period. Didn't get far on Google for help! I work full time and cannot afford to wake up or be up all night awakened from dreams much longer for sleepiness and horrible nausea/dizziness at work the last couple weeks because of the lack of sleep... Thanks in advance!!!
