Isn't that a bit risky though, what if you imagine you are awake and by the toilet and just take a piss? It happened to me 10 years ago! When I woke up it was way too late!

And if anyone is wondering, that extension I have the drill plugged into is 100% homemade. It was originally a variable voltage socket I made with my cousin, it had a dimmer switch on the left but the idiot wired it up wrong and blew the dimmer up. So I just nicked a really long cable off an old vacuum cleaner and wired that up instead so I can use it as an extra extension lead.
