Dream of person, screaming, daughter, heart, mother

I was in a room with my fiancee and our daughter. he had her in his arms and she kept crying to get me. i tried getting to her but something or someone was holding me back from getting to her. i dont know if it was a force or a person but i knew i couldnt move AT ALL. so while i try to get my baby, my fiancee is telling me that hes found a new mother for her and shes (my daughter) forgotten you and doesnt know who you are anymore. he tells me that hes going far away that i'll never see her or him at all never ever. (in reality we're doing well and i never have the worry that he'll take her from me because we've already come to those agreements through court and shes mine). at that moment i start crying really bad just screaming and crying trying to get to her but i was still being held back. throughout all this he kept laughing at me and holding her far from me. he just kept laughing while tears were rolling down my cheeks :( ive seen it two nights in a row and its really scaring me. the tears and his laughter feel so real that when i wake im left breathless in tears and with heart pain. what does it mean please help :(
