you weren't close to LD'ing persay, but you were close to going to sleep. YOu know that slipping feeling that felt like you were going through your bed. That was the sleep paralysis setting in. It's neccessary in order for one to go to sleep. If you kept going you would've probably entered a dream. I say probably because you didn't see any hypnogagic imagery. HI is important in order to enter the dream(but from my understanding not required)

It sounds like you were trying a WILD and i see that you were trying to do it at night. I HIGHLY suggest you NOT do that anymore. Why? Because when you dream you go through periods called REM(rapid eye movement) periods. This is when you dream. For the first 5-6 hours of sleep you hardly get any REM. But once you get to 7+ hours, you get incredibly longer REM periods, thus longer dreams(and most likely more clearer).

If you continued to what you were doing(and didn't let your mind wander), you would've entered a short, vague dream. So that's why most people sleep for the first 5-6 hours and wake up. Then they attempt a WILD and enter the more promising REM dreams.

kinda hope that made sense. If you need any help or advice, PM me and i'll do my best to help you out
