I probably should do an EcoTrain post on Belief.
Most people, i included, have used it wrong.

There is so much that is filtered out so that we can live lives of normal humans.

We don't see echos of the past/future. usually. Many of the deja vu, are such.

We don't generally see angels, demons, fay, the dead (not ghosts), fairies, elves… but they are all there.

But, sometimes you catch them out of the corner of your eye. And then your life changes.
