What do you dream of? Your favorite vacation spot? Endless elevators? Weird animals or vaguely familiar people? What if you could pick and choose what you dream of - even while you're dreaming?
That's what a team of psychologists say they can do by applying a weak electrical current to the scalps and brains of dreaming test subjects.
The subjects ended up in "lucid dreams" in which they could pick and control dream scenarios, just like a video game.
Each night, the participants were zapped with electricity in a different frequency range or – and it’s important they included this condition – with no electricity at all (known as a “sham” treatment). The stimulation was delivered after between two and three minutes of uninterrupted REM sleep. Shortly afterwards the participants were woken and they answered questions about the dream they’d just had.
The group that received the electrical current had a higher degree of lucid dreaming than the control group did.
