To dream of represents your enjoyment of noticing something happening. Watching things that you want to happen happening all by themselves. Enjoying being a spectator.
To dream of kernels represents feelings about the potential to enjoy experiencing something. Getting ready to enjoy yourself or feeling. Feelings about waiting to have to have good time.
Negatively, kernels may reflect feelings about living in a persistent state of expecting to enjoy yourself. Having no control over your life that allows you to enjoy yourself in a stable setting.
Example: A young boy dreamed of being bounced around like a popcorn kernel inside a popcorn popper. In waking life he was moving around a lot, changing schools, changing friends, and even had to change languages at times. The dream may have reflected his feelings about moving around too much making him feel like he was always getting ready to enjoy growing up, but never actually getting to.
