Terrible dreams/ nightmares!

So I've been clean since February 6th 2023. I am on Suboxone. I started off at 24 mg. I'm down to 8 mg. Has anyone else had horrible dreams about relapsing? To me I would consider them nightmares because it terrifies me. It's only started happening in the last 2 days. I wake up short of breath looking for my daughter. Is this normal? Is it because of the Suboxone? It's stressing me out
