look up any word, like pussy:
 
1.
The ideas and plans which stoners make while high, often never carried out due to forgetting or laziness.
Example of stoner dreams:

Kevin: "Hey Ron, we should make a movie about a stoner dude who time travels to the past and people think he's Jesus"
Ron: Yeah dude, awesome idea, we will, one day"

20 Years Later...
no movie

2.
Elaborate plans to do something or go somewhere and participate in an arbitrary activity, usually thought of while drunk and/or high. Then when you sober up, you realize that it's just never going to happen, or is a horrible idea.
Guy 1: Dude we should go rock climbing this weekend, wouldn't that be so fun?

Guy 2: Cmon man, that's stoner dreams, we're just gonna sit around all weekend getting high.
