what happened oml

my school rented out this "inflatable planetarium" and we layed out beside each other and it got really dark and all of the sudden she grabbed my arm. and we thought at one point that the entire thing was falling over (just a illusion) and she freaked out and grabbed my arm again and squeezed it and she didn't let go for a while. and we looked at each for some reason and I felt really happy. ( but the computer wouldn't work so we had to go back) so that "happiness" didn't last very long.
