Pregnant and now MASSIVE ANXIETY TMI

So i had a chemical 3 months ago and now am pregnant, where I’m at it’s past 3 am right now. I just woke up from the worst nightmare in my life. We just told fiancés family and I talked a lot yesterday about the topic of babies and took care of a couple kids yesterday and idk if this is the reason but I dreamed that I gave birth to a preterm dead baby. The dream was so realistic, I lost all the waters and went over to the toilet and the baby went out and I couldn’t catch it properly and it was dead, and I couldn’t support it’s head properly. And I dreamed that I still had a belly and my intimates were in pain and I was barely walking. Then that a cat tried to EAT my stillborn baby. Then in the dream I became depressed, totally lost it mentally.

Now I lay in bed, couldn’t wake up fiancé, he’s a heavy sleeper, and I am wide awake, unable to do anything. I CANT STOP thinking about it. I just had my first bloods yesterday and it all looks good, but I requested all the tests and they forgot HCG (I don’t know how they forgot it, they did all the diseases and morphology and forgot the most important thing), on Monday I go for blood again and on Tuesday I will have my first ultrasound.

Can someone please tell me it’s just a dream and that some of you had a dream like that and everything was okay? Why the fuck some pregnant women have to have dreams like that? Why the fuck did I have that dream. What the fuck, I can’t shake it off
