Abstract noun

My secret is made from a sand rock with a
fossil on the front,
scratch marks of badgers’ claws,
colours splattered over the side of the rock.

My secret is found in a cave where homeless people live,
sitting in the back right corner of the shelter,
and buried under the damp cold sand.

My secret can send signals to space and other dimensions,
and it will not break a single piece of dust
it has lasers on the signal pole.

If I lost my secret it would melt from the atmosphere
and will never be seen again.
