I'd say that's pretty normal for someone rolling, especially on good tabs. I remember one time I was laying on my couch, but in my mind, I was driving on the freeway. I started feeling around the couch and everyone asked what I was doing and I snapped back into reality. I told them I was looking for my blinker. Or one time I was trying to tell my boyfriend to load a bowl, but instead said "deer in the garden of the gods" without meaning to. Rolling balls can fuuuck you up haha
girl i know trips the fuck out like that on md every time she does it at the end of the night. once we were on a sofa watching jackass 3d and she was waving her hand in the air, when we asked her what she was doing she said she was getting the orange remote (there was no remote it was on my pc). and another time we were in a club and she thought there was a sushi bar and not everyone was getting sushi "why are only some people getting sushi?" she said.
