Why everyone is afraid of the dark? Scientists have explained that the brain if it can not explain something properly, it is afraid of it. In dark you can not clearly see and sometimes you can not see at all. Everything seems odd to you due to your brain playing games. Due to the above fact they given Satan the name: Prince of Darkness since they are not able to explain darkness and are afraid of it. The reference to Satan about Satan being the Prince of Darkness in John Milton’s poem Paradise Lost.
What we have written above is also the reason they call the “black” magic “dark” magic or they call the Satanic forces “dark” forces. People give names to things they can not explain related to things they fear or are unfamiliar with.
