Earlier, I used to have dreams. Sometime during my depression I stopped having them. I started going to therapy and few months later I started having dreams again.
So if medication can affect the ability (?) to have dreams, can it also affect nature or tone of dreams?
I used to take an antihistamine called loratadine before bed and it started giving me horrendous nightmares, so yes meds can definitely affect dreams. Doc moved me onto a nose spray called Avamys and they went away (and the spray was more affective anyway)
