I think

When we are young, we're scared of monsters under our beds
But when we grow up, we realize the real monsters are inside our heads
It's known by many names
For the twisted monster, death is one of many games
It favors anxiety, phobias, disappointment, and mostly depression
An expert with lies, making you question
Wondering if Life is just a beautiful lie
Filled with tears and blood upon my thigh
Thinking Death is a terrible truth
Stealing lives and everyone's youth
They say everything's a choice
Makes me wonder, if they've been a puppet, to the monsters voice
