Was it my imagination or was I just high?

I was sitting on the bus and there was a girl in front of me. We kept secretly looking at each other and she smiled when she saw me looking at her.

And suddenly when I pressed "Stop" she turned on her phone and let it out.

She probably wanted my insta or something when I got out

I really regret not having spoken to her.

Or what I am high and it is more imagination what do you say
