I am not sure about meds. I know for me when I get depressed and I have commitments it causes anxiety and at night and in my sleep I will dream about, fret, and worry about whether I can handle them and it just makes things worse. I can look at things rationally and explore options during the day in regards to this but I don't seem to have much control when it happens at night. In this case it is depression that causes anxiety because my confidence goes out the window. But I think it is true that anxiety can cause depression too.

Are there things in your life that may be causing anxiety and stress and may be related to the dream thing?
