Hey Romy, welcome to DV.

I too have had dreams like this. Pretty trippy.

I like Shamanite's advice on maybe changing the dream outcome if you can. Depending on how many nightmares you have. If you're having these dreams a lot without much of them coming true then it'll only have you left paranoid in waking life. I personally wouldn't take too much notice and just enjoy yourself and not worry. Don't let this stop your lucid journey.

I hope you work things out, all the best
