"Inception" is real.

Scientists Insert a Synthetic Memory Into the Brain of a Sleeping Mouse: "Scientists are learning how to insert fake memories into the brain via precise electrical stimulation.... In the latest experiment, they gave sleeping mice a synthetic memory....  "The researchers first recorded the electrical signals from the mice's brains while the mice were awake and exploring the test chamber, until the researchers identified patterns of activity associated with a certain location. Then, when the mice slept, the researchers watched for those neural patterns to be replayed, indicating that the mice were consolidating the memory of that location [aka dreaming]. At that moment, they zapped a reward center of the mice's brains. When the mice awoke and went back into the chamber, they hung around that reward-associated location, presumably expecting a dose of feel-good." http://spectrum.ieee.org/tech-talk/biomedical/bionics/how-to-insert-a-memory-into-the-brain-of-a-sleeping-mouse \ http://classic.slashdot.org/story/15/03/10/1840247 http://www.nature.com/neuro/journal/vaop/ncurrent/full/nn.3970.html
