had a dream I became a mom

I had a dream that I adopted a baby 
I went to this place that just had a bunch of babies that needed to be adopted and I walked over, picked one up and loved him. He didn't even have clothes so I picked him  up, wrapped him in my jacket and took him home. I went and bought a bunch of baby stuff and even let him dry nurse for comfort. I was full on bonding with this baby in my dream. Staring at his face, holding him constantly. I would show him to people because I was proud. He was 100% my baby and perfect. 
I took him everywhere with me. 
Then I woke up and now I'm really, really sad that there is no baby. I guess I'm just hormonal BC I'm on my period. Hormones really suck and I just want the baby back. Like I can't even shake the feeling off now knowing it was just a dream. I still remember his face. Uggghhh 
I really think I might cry over a baby that doesn't exist like wow. What is wrong with me.
