This is a day for going through dream diaries or sharing them with others to wake up to how others have the same dreams whenever they are had of other people due to light and sound traveling so much faster than what we observe as normal time that with our electrical nervous systems we connect during our most relaxed state through gravity... this shows what every person is capable of and tries to warn of things that are wrong to work on healing.. it is also people are educated on showing others the proof of 'dopplegangers' or shared as to how a person may be tricked in a dream to think that a person is actually another person by not showing the face or something along those lines?
On this day people are praised for all thoughts or dreams no matter how dark or disturbing while thankful for the freedom of thoughts and assured that they are merely like clouds passing by that never cause any harm to anyone.
