Dreams of being stalked

Lately I've been having dreams of being stalked and harassed to an extent that has never happened in real life.

For example:

1. I dreamed I was an astronaut on my way to go to space.  (This is not an uncommon theme in my dreams - quite often I'm an astronaut on my way to space when I get interrupted by people being mean.)  I was walking to my spaceship, and this gang of frat boy types came along and kept blocking my path and catcalling me.

2. I dreamed I was grocery shopping, and one of my purchases was a bottle of champagne.  (Yes, from the grocery store. Apparently my subconscious doesn't know Ontario liquor laws.)  The cashier, who was a very tall, large, imposing teenage boy, packed all my groceries normally, then opened the bottle of champagne and started pouring it over the rest of the groceries.  I was shocked and told him to stop, but he just kept mocking me for not liking him pouring my champagne all over my groceries.  I called for the manager by shouting "MANAGER! MANAGER!" and all the people in line joined in calling for the manager, until the manager eventually came over and made him stop. But then, as I walked home, the cashier started following me and yelling at me for complaining that he'd poured champagne all over my groceries.

The strongest correlation of these dreams is computer-related stress.  If I go to bed feeling stress or nerves because of computer issues, I'm highly likely to have a dream of being stalked or harassed.

Psychoanalyze that!
