What herbs will influence dreams?

I would like a list do to the fact me and my boyfriend often wake up screaming in the night. Also, we tend to have flash dreams(the dream we had occupies part of your mind while you are awake) and it is startig to influence him to the point where he is having problems in his waking hours with these. I'm looking for a homeopathic remedy that is NOT marijuana or any other drugs. Thank you:)
