I have to say I don't dream mostly of bad, horrifying things. Maybe you do, or maybe those are just the ones you tend to remember, since they wake you up by being so horrible!
Otherwise, if your dreams are being very disturbed, it seems likely to be that in your life you are struggling a lot, feeling overwhelmed, over-pressured. Maybe this is the case? Are you having trouble in your day-to-day relationships, being pushed too hard at work?
Or maybe it's all the "bad news" in the world, that's making you feel unsafe?
