SP, right from going to bed?

Last night I was up until around 3AM, which is unusual for me. I got in bed and was laying there for a while, when all of a sudden I started to hear a didgeridoo. I think it was auditory stuff, then, with my eyes open, white circles started coming from my eyes and obscuring my vision, then disappearing. I think I started to enter SP because my body became really uncomfortable and itchy, so I was just like 'fuck it' and rolled over and fell asleep.

Any thoughts? Can you go into SP right from going to bed?

You know, I have had a similar experience only one time, where I also was having trouble falling asleep and began to fade into a dream consciously. I know that dreaming right when you fall asleep is possible, but Im not sure if going into SP is. Like I said, I had a similar experience and even thought that I had entered SP too, so Im not calling you a liar or anything, but I just think that we might be misinterpreting falling asleep regularly w/ SP.
But Ive tried WILDing many more times since to no avail.:P
