Sometimes I have one of those annoying dreams where I am late for some kind of extremely important appointment and everything goes wrong. I miss the bus, can't find something I need, didn't realize how late it was... any number of insurmountable obstacles.
Finally, after much anxiety, I awaken and am relieved to find its was only a dream. I often think that death might be very much like that. Like waking up and finding that the life we thought we knew is a mere reflection of the Life that awaits us on the other side.
