Experienced Moms advice please

My baby is now 5 weeks 2 days and I have just given him a dream feed. He usually drinks 4oz every 3 hours during the day and 4oz every 4 hours through the night time, I fed him at 7pm and gave him a dream feed at 11pm (3oz). I was just wanting to know your experiences with giving your baby a dream feed, did they sleep through or wake as usual, bad/good points ?
