Calling lyrics

From the past I can hear the voices calling They call me back Into my darkest nightmare I can´t resist them They try to reach me from their world What can i do? I feel the claws are tearing me apart Why are they doing this? Why won´t they leave me be? Calling! Calling future at the edge of time Falling! I don´t wanna fall into the deepest hole The night is coming I close my eyes and try to sleep And then again I wake up screaming Why are they doing this? Why won´t they leave me be? Calling! Calling future at the edge of time Falling! I don´t wanna fall into the deepest hole Calling! Calling future at the edge of time Falling! I don´t wanna be falling down again! Welcome back! Into your darkest nightmare You cannot run You cannot hide Pain and torture! Will come into your soul No need to scream There is no saviour! Am i going insane?
