Graphic and Disturbing Nightmares: Is It Stress or Medication?

anyone else get really graphic and disturbing nightmares? i don’t all the time but i’d say 70% of my dreams are nightmares and i’m not going to go into detail because it’s extremely disturbing like to the point where some ppl don’t believe me. i don’t enjoy seeing these images trust me, but they don’t disturb my sleep or scare me all that much despite them being so gory. i think it may be the medication i’m taking or maybe it’s my minds way of healing? i’ve been getting a lot better and have never had such vivid dreams in my whole life. it could be due to stress but i’m a lot less stressed than i used to be so i don’t really know.
