What is bedside mode on a blackberry torch?

It's like a preset profile that you can set your phone to whilst you're sleeping so the flashing reception indicator (if on) is disabled or ringtones are silenced for example. Myself personally, I have the options set to disable the phone reception when I switch on bedside mode at night so I won't be disturbed by any phone calls without switching off the phone. I can still use the wi-fi in this mode as well as alarm clock. If you have the phone reception disabled along with bedside mode, you must remember to 'Exit Bedside Mode' otherwis you will be left wondering why your phone has no reception despite being able to do other things.
