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?
Medication can absolutely affect dreams. Flu shots give me weird dreams the first night. Benadryl suppresses my dreams, but the next night they are so intense.
Also, realize the time you wake up makes a difference - if you sleep and wake up naturally you may not remember that you dreamed, but that is very healthy. The dreams taper off as the “awaken” chemical increases.
