Is it normal for a gay guy to sleep with a girl ?

My friend was staying with me last night she woke up this morning crying she said she had a bad dream. She dreamed that she was at a restaurant with her favorite band. A young boy and his father were standing outside. His dad and his gang ran away leaving his son in charge. She said the boy looked like 12 or 13. She said she was pregnant with the lead singers baby. The boy had a gun his dad told him to shot at the singers but he decided to grab a pen and stab people. She said when she ran out the door he chased after her. He stabbed a woman with the pen. Then he grabbed her and tried to kill her with it. But when he did she woke up. She was freaked out. She doesn't want to go back to sleep but it's early she's gonna have a long day today. She said she wants me to lay down with her I don't feel comfortable doing that. She said she feels sick. With all these shootings been going on lately she's been having nightmares. Is it normal if I slept with her ? What should I say to help her feel better ?
