OBE - WILD relation

I am getting very curious about this relation. So far all of my WILDs happened in OBE form. The order has always been like this;

waking up after 3-4 hours of sleep => staying up 1-3 minutes => SP => OBE

Although I never visualize being out of my body, it always happens like this. The room is always my room, but as soon as I went out of the window, scenery changes drastically.

i believe ill try this. tonight. but what do ya use to wake yourself up after 3-4 hours?

Well... alarm clock :D But strangest thing happening these days; for example if I went to sleep at 2 and set the alarm to 5.30, I'm always getting up by myself around 5.
