I'm not really sure if it would work or not. I mean it does seem incredible, particularly emotions.

For physical sensations the switch could just be another way to associate a sensation. I don't think there's any experienced lucid dreamer that hasn't done that.

I've never induced an emotion in a dream. I don't even think I have many memories of emotions in dreams other than fear and awe.

I wish I could start lucid dreaming again. There's a bunch of experiments I wish I could do.
