the coolest thing about lucid dreaming is the ability of control. you can eat a taco and it will taste like a taco, you might get full, but it depends on how well you can control the dream. if you've got really good control you could eat thousands of tacos and never get full. it's all about control.

if you have sombody in real life that you dream about and fell for them in the dream, you might fall for them in real life. wierd, i've never thought about that before.
