Do 6 month baby still need to dream feed?

Hi my baby is now 6 month plus and her last feed of the day is 7pm and then she will sleep throughout the night till the next morning at 7am. She did not even wake up or cry for milk but i use to dreamfeed her at midnight worried that her tummy empty for too long. It is ok to skip the dreamfeed and that means like 12hrs without feed, is it ok? Day time she ate and drink well about 800-900ml fm.
