For me, it all began with eyes closed.
It was the only way I could shut the world out which is what I thought we were supposed to be doing. Almost like closing a door.
Don’t disturb me I’m concentrating.
But for many I know eyes closed is more ‘fear inducing’ so they prefer eyes open.
I then found that having my eyes closed helped me to be less distracted by my surroundings. The trouble was I then began to rely on having my eyes closed, I felt it was the only way I could do it and it had become a habit.
