In 1973, the best selling book, The Secret Life of Plants, by Peter Tompkins and Christoper Bird showed how plants feel and respond to human stimuli and care. Like telepathic communication with animals, much of this evidence was rejected by the mainstream scientific community and those who looked at animals and plants as non-sentient.

Throughout history, people have had awareness and relationships with unseen spirits in parallel realms to the physical world.

Those who have a close association with nature may perceive spirits around the plants or other natural areas. They have been called fairies, nature spirits, devas, sprites, or other hidden folk.
