Ok, this has happened to me four times now, three times while napping, once while DEILD.

I start off by performing SSILD, then I get hazy and tingly. This is normal, right? Well, apparently you're supposed to keep doing this till you fall asleep, but the thing is, I don't. Instead, my head starts to feel like it's leaping, and my ears ring obnoxiously. Usually after that, it feels like I'm looking into a strobelight. After a short time, I feel like I'm whirling, usually towards the right. Then I get these crazy images that make NO SENSE. The third time I managed to get a WILD. I know this is gonna sound pathetic, but I was just staring at a cup of yogurt. It felt like real life, but then I felt myself floating away from it and back into reality. But wait! It gets better: I'm just about to pull myself back into the dream, when my dad calls me.

What I'm wondering is-- how long should I let this jerking/spinning take place? Cause if I let it go too long, everything stops, and I'm back to reality. But somehow, I managed to let it spin me into the yogurt dream haha. But it vanished too quickly for me to even do an RC. Someone told me to roll over when I start "spinning", but I'm afraid that if I do that, I'll just wake up. I was also told to do a RC as it was happening. But do I RC mentally or physically?

Here's some extra info:
-I've never had a LD, except sometimes when I use it to wake up from nightmares
-I tried doing this again today, but nothing happened except for a numb feeling
-I have extremely vivid dreams, one of which I was actually talking to someone about lucidity but never actually became lucid

HALP!!!
