Auditory dreams

Hi Again!
Had couple more message-type dreams before I got up this morning.
I say that because there's very little visual that I can recall.

In the first one seems I was discussing cancer. It went something like this: "The treatment makes you so sick, you're barely alive.
And they call that living? Well I would rather die!"
Must've woke and went back to sleep...

I had borrowed a pen and was trying to give it back.
(Evidently they had told me to keep it)
"No", I said, giving it back, "that is your life."
Holding up a pencil I said,
"This is mine."

The thing that struck me most was that anything written in pencil is erasable. So how do I go about erasing my past?
