Does this mean anything?

So there's this girl and we were doing a project together and she leaned over the table really close to me. She does this sometimes. Also I noticed that today she started wearing whatever the, uh, female cologne, whatever it's called. She's not going out with anyone and so I don't know if its a coincidence or if its connected to me. I've also noticed that she brushes me sometimes (no, not the haribrush brush, the other one - I would know hair brushing would be a sign, a sign of weirdness); is this a sign or is it just me over-analyzing. Does she like me? Are these signs?
