Never did a dreamfeed with John as I didn't read the BW until he was 4mos, but he slept through 7-7 at 8 weeks. With Zoe we always did a dreamfeed and at around 8 weeks dh said he was too tired to do a DF so I said let's skip it and she has slept through ever since. With the dreamfeed she was waking at around the same time as your little one - could be just coincidence too
I say try dropping the dreamfeed; bascially 3 things could happen-
1. She sleeps through entirely
2. She wakes up twice vs once
3. She wakes up once like she does now with the DF
If her bedtime is after the last bottle at 7:00 then that's good. 2, 5 and 7 is acting as a clusterfeed. Tracy recommends if one isn't working, concentrate on the other.
Let us know how it goes
