Lucid Dream Control Issues
So last night I was dreaming I was outside in a parking lot during nighttime and I just had a random realization that I was dreaming, so I started to stabilize the dream, so I started to kneel down on the ground, but I couldn't seem to bend my knees for some reason, the feeling was like if my knees were magnets and the ground was repelling my knees so I couldn't reach the ground and start feeling the texture. I then gave up trying to feel the ground and started to feel my face, and it seemed to work, I could feel my skin and I was able to stabilize the dream.
But right when I was stabilized I suddenly heard someone say "smile" and then my vision went completely blank, and I started hearing loud static and feeling "static" or "fuzziness" and for some reason I started to feel extremely scared even though I was just hearing static and I started to scream. I then woke up.
So my questions are:
1. Why couldn't I kneel down?
2. Whoever said "smile" what did he say it for?
3. Why did I loose my vision, start hearing static and start to feel fuzzy?
4. Why was I scared, even though what was happening wasn't scary and I could stop it if I wanted to?
