*I've underlined the questions because I'm aware I wrote long.

So, I went into my LD and then I was really frightened because at that time I was only familiar with Lucid Dreaming by fear. And so I felt this great pressure to my left being pushed and I tried not to put my focus on it because I didn't want to believe what was going to happen. But it happened anyway. I was tossed across my room by air force(as I recall thinking it was a demon or some kind of evil spirit) and just was being moved around and controlled. Literally I had no control over myself. That's why I had attempted to called out to God and had myself awake. (When I was calling out it was hard moving my lips but I had focused on the word and kept saying it over and over again until I was finally able to hear it all the way. Resulting into waking up from my own voice.) Has this happened to anyone? Have the dream control you? Like you have NO idea what's going to happen next. You can probably expect ANYTHING really...

I was also wondering if in lucid dreaming it can also have daylight. Cause I noticed my "dreams" provide day night but noticed that my LD's are usually dark.

Also, every time I LD I can BARELY move. I have to put most all my power in just to move my body. Eventually my dream gets me and it starts to control me. Or, I get tired and scared and call out to God once again. But except this one time when I was lucid dreaming I was able to walk around. I guess because I wasn't sure if it was reality or not...but since I was leaning towards reality, I probably gave myself enough confidence letting me be able to walk around fine.(Obviously I was still dreaming.)
And I wasn't scared...so probably all this has to do with my fear?
Unless minus the fear and you guys are also experiencing or experienced the same?
Anyway, I want to have full control...
How should I do it?

Also, would it be a sin if I have sex in my dream with control? Cause I remember the last LD I had, the 3rd thought I had was, "find someone to have sex with"... It's because I'm a virgin(I'm well aware this is really bad because letting you guys know, I"m only 15.--But the closest thing I've ever come to anything sexual with anyone was just a peck on the lips.) and I want to stay that way until marriage. I'm trying to be a role-model/responsible Christian. But obviously as a human flesh I'm well familiar with sin being tasty and pleasuring. As of me going through high school where all around is hormones and aware of people doing 69, giving birth, sex, blow jobs, and hand jobs... temptations been hitting me hard. Well back on topic, I'm looking forward to answers, thank you!
