Is she interested, or just teasing?

Anonymous
Tonight I received a snapchat out the blue from a girl I used to flirt with heavily about 7 months ago. In the snapchat, she was in laying in bed with her cleavage showing. We exchanged a few snaps and were flirting a little and she said that she was "trying to get me to cuddle" with her. I told her that cuddling was pretty great/etc and we kept on snapping. Out of the blue I noticed that her bra had disappeared and she was becoming a little more flirty. I sent her a snap saying "You seem to be getting comfortable!" and she replied with "I sleep naked, good night!". I don't know what to make of this as we haven't really talked in a few months and I am kind of skeptical that she was just teasing me. At any rate I sent her another innocent snap asking her for her new number, because she kind of rekindled my interest. (I was pretty much just sending selfies, not into the whole dick pic thing.)

Well to add, she sent me her number via snapchat and the picture was another of her without a bra on, in her blankets, and we texted a little today. She also sent me another provocative snap. Does this persistence mean anything?
