Here are some frequently asked questions we receive about dreams: Does the content of a dream have any meaning? Can friends and family members who have passed on visit us in our sleep? Is it
possible for dreams to be precognitive, foreseeing future events? Does lucid
dreaming enable us to travel out-of-body?
There's really no way for us to know for certain whether visits from deceased individuals and precognitive or lucid dreaming actually occur. However, there is a difference between what we speculate might be possible and what science-based evidence tells us is likely probable. SciShow’s “The Science of Dreaming” explains what goes on inside of our minds and bodies while we sleep and why our dreams are so important to our waking lives.
When someone claims to have seen a ghost, what exactly are they seeing? Perhaps they have been witness to a physical manifestation of the supernatural, on the other hand maybe their mind was misled into perceiving something that wasn't physically present. Let's return to the elementary of understanding how it is we visually perceive our world in general with another fun video from Technology, Entertainment, Design (TED).
