Question on Dream

I had a dream last night about my father calling me and telling me that my mother died at 4:00 in the morning. I called my mother today to tell her my dream and she said that she awoke at 4:00 am and thought that her house was on fire. She smelt and saw smoke but when she turned on the lights nothing was there. We both had a hard time getting back to sleep. Is this a coincidence or is this a psychic connection? Thank you for your help
