It is surprisingly easy to fool your brain into making you feel a certain way. By manipulating your brainwaves you can slip into dream states without going to sleep.
IF you've ever tried out a virtual reality headset, you will understand the disarming sensation of pulling the headset from your eyes once it's game over.
It's incredibly easy to trick your mind into feeling sensations like fear, panic or even total calm and now - according to scientists in London - dreaming.
Scientists claim to have put people into dream state while they are awake simply by listening to different frequencies
Scientists are beavering away at methods that can hack our which, similarly to virtual reality, can coax the brain into changing its perception of what's real.
A group of scientists in London are putting volunteers into a dream state - even though they are awake.
Carl Smith, director of the Learning Technology Research Centre (LTRC) in London told IFLScience that they have been successful in the process, called "context engineering".
They can do this using a method called binaural beats, where a tone of a particular frequency is played into one ear and a different tone of another frequency is played into the other.
By listening to two different frequencies in each ear, your brain will create a third to balance them
The brain tries to regulate the sound and creates a third tone that balances the two by creating an equal frequency.
Focusing on this third tone, a method called "delta entrainment", allows people to drop into a dream state – without going to sleep.
Smith said:"When people want to go into a dream state they can do a 15-minute delta entrainment so their brain actually goes into the delta state, a sleep state, even though they’re not sleeping – and that’s just through listening to binaural sounds."
It's not just for inducing different levels of consciousness, these methods can help us regulate sleep patterns, calm us down and help us focus, they claim.
Scientists hack mice brains and make them freeze
There are a variety of exercises you can perform to train your brain into focusing on senses we typically ignore.
This includes concentrating on your peripheral vision, to gain a sense of calm, something athletes are adopting ahead of a race to focus their mind.
It's part of a subculture called biohacking, which has gained notoriety among amateur scientists.
DIY hackers are adopting methods that originated in a lab and are tinkering with their bodies in their bedrooms - sometimes with disastrous consequences.
In one extreme case, a group of Californian "scientists" said they had given a colleague night vision after injecting his eyeball with a chemical found in deep-sea jellyfish.
There is a growing community of transhumanists who believe implanting things in their body will "upgrade" humanity and that we will eventually merge with machines.
The concept of singularity, where humans evolve to merge with machines, is a concept that's been brought up by Tesla billionaire Elon Musk and discussed by Brit boff Stephen Hawking.
