Did I just WILD?

Ok, so I haven't been practicing WILD recently because I've focused more on MILD. I went to sleep at 2am with the intention of waking up early in the morning to do a WBTB. I woke up at about 6:30am, got off my bed, went downstairs, and drank some water. I then went back into my room and just sat there for a few minutes, telling myself that I will have a lucid dream. I then tried to go back to sleep while saying some mantras like "I will become aware in my dream and I will do a reality check". I lied on my side and suddenly, I hear a sort of high-pitched sound from my right ear (since I was lying on my left side and my left ear was buried on the pillow). Then I started seeing like a white spiral on the back of my eyes. Then my legs started to feel weird and kind of numb. I assumed I was going into sleep paralysis so I just lied there motionless and tried to see what happened. Everything that I just described - the sound and legs-feeling-numb and the spirals - all happened like simultaneously. The first thing to happen was the sound coming from the ear and then the rest happened at the same time. Eventually, everything was normal and the spiral that I saw disappeared, as well as the sound. Anybody explain what just happened to me?

Note: This was not an intentional WILD. I was only trying to do MILD.

You experienced some hypnagogic hallucinations which are the signs of an impending dream entry. Probably, you got too excited which is pretty normal and the process aborted. Its also pretty common to WILD when you are using mantras or self suggestion - as it is indeed one method to WILD.

I wouldnt really saw I was "excited".. more like I was shocked but also confused.. Part of me did feel as if I was going through a WILD but I really thought it was just a coincidence.. I simply just kept my eyes closed and wanted to see what would happen if I just didnt move.. Like I said, eventually everything was back to normal and I actually had a hard time falling back to sleep for some reason..
