What's going on? I'm so confused

I'm new to online dating so I don't know if it's common or not. I've been talking to this girl. In my previous post, I've already said that she is a dry texter (I am not that good either let's be honest) and I thought she ghosted me. But she actually replied later with "😴" at night 😅. She now replies within 24 hours but her replies are still "hmm/yea". If I try to be a little bit humourous, maybe little flirty she just replies with "😂". Idk what's going on? Is she into me or is she just trolling me? Or am I just a noob?
