Sounds like a WILD to me. You entered a dream while falling asleep and still had enough awareness to do reality check.

Please, read some of the latest threads in WILD forum about SP. You don't need it to WILD. Most people don't get paralysis. Sometimes you don't even feel the vibrations or other types of hallucinations, especially when you fall asleep fast, as you sound like you did.

It's really silly to deny that someone had a lucid dream, just because there was no SP.

And you woke up, because you probably were excided. And I would also say, that you didn't have enough time to fall asleep deeply enough. That happens to me more often than I would like.

So congrats on your WILD. I bet you'll have many more now. Here is a great tutorial that will answer all your WILD questions. Happy dreams
