Dream About Being Pursued By Aggressor

I crossed path in a classroom with my aggressor who wanted to kill me in real life. I decided to scream unapologetically the truth about him in front of everyone. He shifted and started pursuing me. The dream was about him running after me. Everyone in the poursuite was disguised as someone else. I apparently was vomitting when feeling bad so people were scared and ran away from me. I asked my crush while holding her fingers to help me and stay with me. A friend literally saved my life.
