Hey guys! I have a friend who's been struggling with nightmares (happens almost every night which causes him to not sleep well) and I think that might have to do with his depression. So I wanted to know if this is a common thing and how I can help him with that or tips I can give him to help.

Ps: I thought it might have something to do with the anti depressive pills but he talked to his psychiatrist to adjust medication but it didn't work.
