Human and Plant "Photosympathy"

[Unbound]

Can't get anywhere without the starting ideas! True, in terms of empirical "facts" there isn't much correlation, but good food for thought.
Also, while psychic vampirism could be one way of viewing this, all of the "positive radiation" we talk about would be along the same lines, it's not just about absorbing energy, I don't think, which is a negatively oriented view of it.
