First of all, Hi!
I've visited the site before and read the tutorials but I'm new to the forums.

I've been experiencing with WILD for a little while now but have never managed to succeed.
But something weird has happened twice (once a few weeks ago and now again on this morning)..
Both times were in similar circumstances- I had the chance to sleep in and had already woken up 2 or 3 times.
Now when drifting off again all of a sudden I hear a loud sound and black and white stripes start flashing in my vision faster and faster.
I was quite awake already since it had already been about 2 hours from my normal wake up time so the first time I could only sustain it for like 10 seconds or so.
But the second time (today) I think I might have managed 30-40 seconds.

The question is, what was the phenomenon? Was I on the edge of a WILD?
I didn't experience SP.

Thanks!
