Here's a question... Does stress cause really horrible nightmares? Last night I woke up from a horrific one. It was about my elder brother, I dreamt someone murdered him and the grief just consumed me. As of late these nightmares have become frequent and I end up waking about 6-7am instead of 8:30 in a bit of panic, heart really beating very fast and cold sweats. Can anyone recommend what I can do to get rid of these unwanted and frankly scary dreams? They say it's usually because of an unsettled mind, which is true ATM.
