Srry to say this bad I don't think its normal. Tell maybe u have a horrible life or something or maybe you've been traumetic or something or maybe you its because the only thing u think about is bad things. Just keep living and think a happy life and thoughts ok.
On a 1000 ways to did they said a gurl died from that because the dreams were getting more intense n its actually a medical condition Bt I don't member tha name Bt watch tha show n u should find it
Its not that I would say it isn't "normal" but it isn't good. I would speak to a therapist because on average that doesn't just happen over an extended period of time.
