Yes, the dreamfeed may have something to do with it. If she's not getting a good deep stretch of sleep she may not have the right sleep stages for the rest of the night. Sleep changes around this time, where their sleep cycles become more like an adults than a baby. If you can drop it, you may see a sleep change in a week or so.
She sounds like she's perfect for a 9 month old, 3 solids meals and 4 milk feeds. Around 9-10 months some babies will drop to 3 milk feeds, some will keep 4 until 11 months or so and then start dropping. Each baby is so different.
Mine were waking around 9-10 months for teething and because they both learned to pull up and cruise around then. Is your baby doing anything (or about to) developmentally that could be causing the wakings? Do you feed her when she wakes?
