Triangle shape craft over 2nd story apartment

I was lying on my couch, with my newborn baby...maybe 3 weeks old. Something spoke to me...telepathic. female voice said to come to window and bring baby. I felt very calm...very peaceful and I trusted it. I went to big front window...some how I knew to look up. To my surprise. There was a triangular craft hoo ering over the roof. No lights...bit i and no sound at all. I was so close I could see 3 lights...one in each corner. Looked dark Grey. I remember talking to them telepathic and said "by the time I get my husband, you will be gone. " also, I should mention it was about 12:30am...so husband and other 2 children were sleeping. As I walk in the bedroom to wake my husband...the time was almost 2:30 am. It only seemed like a couple minutes. Of course it was gone when my husband looked. To this day I don't know why they wanted to see my baby. Also, why almost 2 hour gap in time?
