Three interesting dreams

Last night I had not one but three interesting dreams. I felt like describing them and here seemed like a reasonable place to do so.

The first dream:
I was outside the house where I grew up, although it was in a place that isn't familiar to me in waking life. I was building a wooden bridge across a small stream. I had a suspicion I was just dreaming because I don't normally go outside with no clothes in real life. I also discovered that pinching yourself to see if you're dreaming is not an effective strategy: it feels pretty much the same as it does in real life.
This dream I feel is most likely to have a significant meaning.

The second dream:
I was riding my bike round some park by a lake trying to figure out where the exit was. I don't know what lake it was but it was one of those really intense blue ones. There was pretty lush vegetation both in the park and on the other side of the lake: a lot of ferns and that kind of stuff.

The third dream:
I dreamed I woke up (first time that's ever happened to me) in my own bed but in an unfamiliar room. Kinda ties it to the first dream by having a familiar object in an unfamiliar place. Anyway there was a party going on in the hallway and some guy with a South African accent was wanting to introduce me to all these people and I just wanted to eat breakfast and take a shower.

I wish I knew more about dream interpretation.
