Cover art for Trapdoor lyrics by Twenty One Pilots

I personally think this song is about a closeted transgender person, who's trying to hide their real identity from people who wouldn't accept them.

The line, "He wakes up early today ,Throws on a mask that will alter his face" would mean covering up who they really are and then the line, "Nobody knows his real name, But now he just uses one he saw on a grave" Meaning no one really knows what their real name is, only their birth name which is otherwise known as a dead name.

Then there are the lines, "And he pretends he's okay, but you should see, oh Him in bed late at night, he's petrified" Meaning the person is not okay with faking anymore but they're too scared to come out, and then there's the line, "Take me out, and finish this waste of a life" would mean that he's sick of living the way he is, and would rather die.

And then there's the chorus, "Everyone gather around for a show Watch as this man disappears as we know Do me a favor and try to ignore As you watch him fall through a bleeding trapdoor", this interprets that though he may seem real, he's not, he's acting, or putting on a show, he's fading and disappearing bit by bit and everyone else is ignoring it or not noticing it.

After the chorus, there are the lines, "He thinks that faith might be dead Nothing kills a man faster than his own head" which would mean putting himself down and feeling like no one would accept him, so he keeps these thoughts to himself, slowly letting the thoughts in his head kill him.

and then the lines, "He used to see dreams at night But now he's just watching the backs of his eyes" as in he used to be able to sleep okay, but now the thoughts of being disowned or bullied haunt him at night, rendering him unable to sleep, or see dreams

After they repeat the pre-chorus and chorus, there comes the line, "'Cause nobody knows he's alive" Meaning no one knows who he really is, the person he truly is, doesn't exist to them, meaning they don't know that he's alive
