*cracks knuckles* One of my talents, believe it or not, is dream interpretation. I'm not even kidding. ;)
So, let's start with the basics, Snorg. Dreams about sex in any manner are often triggered by one of three things: Your body shifting position while asleep, hormonal changes, or random thoughts crossing your mind.
In the first case, the dream will often be meaningless and will simply be a reflection of the things you were subconsciously thinking of when your body changed positions and triggered the dream. The brain tried its hardest to fill the void of interpretations and just pulled stuff from the top of your mind that somehow made sense. Given that those things were all retro systems, about the only meaning you could pull under these circumstances is that you've got retro systems on your mind and haven't had much of a chance to think about other things.
In the case of hormonal changes, most of the rules of the first case apply and the dream is likely meaningless. However, those changes in and of themselves could be a result of any number of physical factors, but the dream doesn't seem like it's imparted any information that would make it easy to figure out what.
In the final case of random thoughts, this is when the dream is going to potentially have some meaning. Under these circumstances, my conclusion is that the dream is telling you that whatever your current or next retro project idea is, it's probably going to overwhelm you. Here's how I came to this conclusion:
To see others having sex in a dream symbolizes some form of desire and completion. Since the things having sex are retro devices, and since to you, retro devices are one of your favourite and most important things (this is an assumption), it stands to reason the dream is relating to said interests.
Then they give birth to expansion boards, specifically suggesting newness. Combined with the first symbology, this suggests a new idea related to your interests.
But then they swarm you, suggesting that whatever this idea is, it's going to potentially overwhelm you.
Now, this isn't necessarily a BAD thing, since maybe you want to be overwhelmed. After all, your mind chose sex as the best way to convey this line of thought.
So, if the dream was indeed triggered by your mind and not by your body, that's the most likely meaning behind it. Otherwise, it was just something extremely random and means nothing. :P
