Is this dream normal?

About three to four days ago I had one of the realistic dreams I have ever had, and trust me I have a lot. This dream started out as a normal dream, until I remember being in a bar sat down with a girl to my right and someone I was associating with. As the girl to my right had gone to the toilet I remember talking to this man who I've never seen in walking life about how I needed a job, when a gypsy looking woman(that's the only people I've seen who look like this) wearing a read dress with a robe around her head covering her face only revealing her eyes and I remember them being an sharpe green, she walked other to me and said that she had a job for me I carnt remember what the job was but she said that it had to be done by March of next year, at this point my body had become coconscious, by that I mean I can fully controll whats happening in the dream I ask her why the job had to be done by the date she said before. She looked at me and said haven't you heard? And I asked what? She replied by saying that the worlds going to end on March the 15th 2016 I laughed and asked how did she no and she placed cards on the table, the cards had pictures of asteroids and writing below saying that an asteroid will hit Earth on the 15th of march2016 at this point i had been scared at what I was seeing as the longer I was looking at the card the more my heart shrunk and my breath had been shortened. With that I've put the card down and the dream goes back to normal the girl came back from the toilets and there was no sign of that woman again. I have had a dream prior to this one when I was younger and I can just remember me and friends where outside when all of a sudden the sky turned red and we was running for shelters in sheds. I don't know hat to think some tell me this isn't any seirious I dont wanna die
