Hi,
These are music lyrics. Music lyrics can be difficult to make sense of as they may mean something else (we call this a metaphor in english).

This person feels like he is slipping of the edge of something, for example a tall building. He is using this as a metaphor for what he is feeling. He is feeling like he is slipping off of the edge of something, or about to fall.

I hope that helps. Music lyrics are difficult to understand.

Please, what is the meaning of this sentence: " I'M SLIPPING OFF THE EDGE" ?

Everybody's screaming
I try to make a sound
But no one hears me

I'M SLIPPING OFF THE EDGE
I'm hanging by a thread
I wanna start this over again

Thank you so much. :)

I'M SLIPPING OFF THE EDGE can be seen as a metaphor; in this case the person is about to loose it's mind, something is upsetting her / him in a harsh way, as if the person will forget everything / everyone, as even life doesn't mean a thing, so the person wants to "start over again".

I hope this help you understanding the sense of it.

Cheers m8.
