ELI5: Explain Like I'm 5

Consensus reality

Consensus reality is when everyone shares the same idea of what is real and true. For example, if everyone in a classroom believes that the Earth is round, then they all share the same consensus reality. Imagine that your classroom was split and each group was asked if they thought the Earth was round or flat. If one group said the Earth was round and the other said it was flat, then they would not be sharing the same consensus reality.
