When a person refuses to see what's in front of their face they will lie to themselves and say "that's not real" either out of fear or/and disbelief.

To them to admit it - means they're going crazy or they feel others will look at them as such.

But no matter whether we choose to believe or not, it will not change the fact that it is what it is, and it was what it was.

The best part of it is - you're not crazy nor were you seeing things but then again you were seeing things...
