Moments in time, when you feel alone
Whether in a crowd, or alone at home
An invisible shield, wraps you around
Emotions empty, hear muffled sounds.

Penetrating shield, hovers as cloud
A cotton wool cocoon, soft not loud
A rush of wind, as music or a voice
Drifts in space, you have no choice

Then it ends, as a voice may reach
Through cotton-wool mask, it seeps
As waves reach shore, dragged away
Moment may pass, but memory stays

Of times in shock, reality got lost
You couldn't focus, considered cost
In life we cope, with variety of pain
Tears may fall, human type of rain

Each hurdle passed, strength becomes
Our shield of life, as thoughts run
Any experience earned, our defence
Instigates warning, with common sense
