Simple dream? Or nightmare?

Ok so weve been ttc for almost 3yrs now. Emotionally its becoming draining for me. Each month a disappointment. Everyone around me announcing their pregnancies, having their babies, enjoying the lime light. I feel like a spectator. Lately Ive been having dreams. Dreaming Im pregnant and giving birth via c-section but theres no baby at all. Just the birth and the pain afterwards. Baby gone. Or like the dream I had the other night. In the dream I was looking after my sister-in-law's baby, enjoying every moment. To have my brother-in-law to come and take her and telling me I can take care of her coz I dont know how its done. In the same dream I came across a baby boy. Abandoned. I took him in and started taking care of him. I received a phone call from someone telling me that I should keep the baby because the mother is nowhere to be found and that hes mine now. After a while, some woman came (a friend of my sister-in-law) and took the baby from me telling me that I cant take care of the baby and only she knows how to do it. Asking me why would I wanna keep the baby after I already had 2 children. Is this normal? Am I becoming mad now?
