NIGHTMARES AND PREGNANCY PLEASE HELP

Be
Does anyone have nightmares during pregnancy? I had a nightmare that I was locked in this house.. I was hiding and I was staring at this door thinking and knowing someone was going to come and I was scared I knew this person was bad. I was staring at this door I had a plan that if this person came from the front door I would run out the door I was staring at and escape. But that's when I saw this white pale hand with black eyes close the door I was staring at the only hope of escaping. I heard thud of him walking towards me and he found me. This souless man was bald pale white and had the blackest eyes I ever seen. Next thing you know he was stabbing me repeatly. I swear I felt the pains of every stab. On my arms, face, neck and everywhere. They were intense and I felt like couldn't breathe and then I woke up sweating and breathing hard. I have had a nightmare that I felt so real. That I actually felt pain. I'm scared to sleep at night afraid of another nightmare. This isn't the first nightmare just the scariest.
