Deep web is like the basement of the internet. The 'normal' internet that you use every day is like the first floor of a house. The deep web is like a basement that is hidden behind locked doors. The deep web contains websites that are not seen by search engines like Google and cannot be found in a normal internet search. To access the deep web, you need special software called a 'tor browser'. The activity on the deep web is not monitored, so it is possible for people to share information anonymously.
