Okay, so I've been trying to have an LD for a while now. I've also been wanting to see if I could do SP. But no luck. Until last night. And I'm trying to figure out what happened...

So right before I went to sleep I was thinking to myself that no matter what I dreamed, it would happen in the future, just as a joke. So I proceeded to have a dream about my car getting covered in snow, then it got wrecked, but then it turned into my moms car and switched locations and a semi was about to run into it when I said to myself, "Well no way this is gonna happen in real life." And at that moment I felt a weird sensation come over me, as if I was being pulled into the dream, perhaps about to go lucid, but then I got super excited and woke up, but not entirely, I felt a weird feeling shoot through my body and I heard s sort of rhythmic drumming and I felt tingles all through my body. I thought I had reached SP, because I couldn't move and it was just really weird.
But since I was so excited that I had gotten into SP, I couldn't go back to sleep, so I forced my body to move, and proceeded to fall asleep. Nothing else happened that night.

So I'm just wondering what happened. Was I about to go lucid? And then lost control and woke up in SP?

If this happens again in the future what should I do to stay in the dream or go back in once in SP?

Thanks!!
