I get molested in my dreams

I'm a teen female, I have trouble falling asleep and my Sleep schedule is fucked. I don't even usually have dreams, but when I do they are extremely weird. Last night I dreamt about a random person calling me constantly, and I am not picking up his calls..but when I finnally do pick up one of his calls he asks me to sleep with him. One other day, i dreamt about walking on the quite road at night and some man starts following me and when I start to run he comes after me with a knife. Is it a psychological issue?
