Dream About Strange Injections And Being Pregnant

My dreams started with me being in school and starting my first lesson for doing gellac nails and my teacher brought me to this building in our school that is for disabled children and thats when the lady start getting her things out and I seen her taking it out like I was laying down but looking behind at her and then my teacher put needle into my arm and insert some injections and then she put 2 more on my stomach and on my right leg and then I couldn't feel a pain at all and she cut up my leg like fully and then i realised what's was going on I couldn't move but I started crying and then when they finished she told me I only did what's good for you and I told her that how was I pregnant and why did she killed My child and it was baby girl as well and she said I seen u r pregnant for awhile now so I just helped u and she left so I tried to start walking and I was crying even more but I start shouting alan (my bf name) and saying what just happened and he disnt seem too much interested even tho in his family they could never get girl so I was surprised by it so I started crying even more and then my dream turned into being in some different country and I dont really remember what happened but everyone was trying to get it but they were like some monsters and all andbefore it started I was outside brining those people to survive and I brought my dog and cat inside as well and then when it stated I tried my best to close all the doors and everything wil they tried to get it I remember it was so difficult for me to do but while I was dreaming and in this dream I thought to myself that ages ago I had this dream and how is it possible we can dream about same thing again
