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?
Both the psychiatric medication and the mood fluctuations (in this case, from your depressive episode) can alter sleep and dreams. Also, if you’re AFAB, your monthly hormonal cycle can also alter your dreams, especially before menstruation.
