This isn't my first attempt at a WILD, but I think it was my closest one. So here's what happened:

I drank some water before bed so I would wake up in the middle of the night. Then, I went to bed, and woke up when it was still dark to go to the bathroom. I couldn't tell whether it was close to morning or not, and I thought that going into the kitchen to check the time would make me too awake. I decided to go back to bed and WILD anyway. I was still for a while, and concentrated on my breathing. I got as far as 400-500 while counting my breaths. But after hitting 500, I decided to get up and do a few RCs, which told me that I wasn't in a dream. So I went back to bed and started over again, going through the same process as before. Soon, I started seeing very vivid scenes, which I figured meant that I was close to entering a dream. In my room, I have a clock that hangs by my bed, and it ticks quite loudly. It was easy for me to ignore, but every time I went into those vivid scenes, I would get distracted by the clock's tick, and pull myself out of them. I think that's the reason I failed at it :/

Question 1: Was my clock the reason why I failed my WILD?
Question 2: Were those vivid scenes actually the beginnings of me entering a dream?
Question 3: How are you supposed to feel when you enter a dream from a WILD?
Thanks!
