In the part where Commander Sisko is inside the orb,he gets a fantasy/flashback thing to when he first meets his wife,Jennifer.

The story is:He was walking on the sand of the beach,and it burned his feet,so he ran unto a the nearest towel,and Jeniffer was lying on it.They met,and then walked down the beach.

What I don't get,though,is how the sand could change temprature!At the beginning,the sand was burning his feet.About a minute later,he and Jennifer were walking along,and the sand was suddenly cooled down!
