I'm not sure what to do?

I met this girl at a friend's house one night and anyway I ended up coming over a couple of times and hanging out with her and she is cool as fuck to. So I noticed this little tik or whatever it's called where she would go woo here and there and okay ya know hell it doesn't bother me its kinda cute even. So I come over last night because she asked me to and when I got here was like what's up and then we go in and she is cleaning her room and I'm like what's up cause she laughing and nothing, we go back outside smoke a joint and yeah she goes in and she sounds like she is talking to people and nobody there, a little while later she sitting in chair and with both legs is stomping on the ground and laughing and I'm like wow what's up and she laughing saying nothing.

Next morning we wake up and sit out in the garage and we the only ones here and she goes into a different room when I go into a room she is in and I just hear all this talking and she loudly having conversations in there and sounds like with multiple people and what should I do y'all?
