Why do people call Ep's Ap's?

On a horse there is Jason , a guy that has past life memories of having been a horse .

OMG... I think I heard his story on Coast to Coast one day. More than a little odd, but oh well, lol.

I remember him talking about how he missed having a master so much that he wanted a surrogate master in his current life

On Jason the horse , he has been  on coast to coast a few times .  The way he tells his story he is very believeable .
