The sensation of ...was just off the page. What does this phrase "off the page" mean?

Also: ...is sending me "over the edge". Please explain them to me. Thanks a lot.


"off the page" is probably very intense, undescribable
but in other contexts is detached, originated in a written page of fiction.

... is sending me over the edge: ... driving me crazy. (That is my guess, let's hear native speakers' opinion.)
