Lucidity problem help!

So.. like 30 minutes ago i had my longest lucid dream ever, like 10 minutes or something, but the problem was that it was barely vivid.
This is what happened. I went home, but it wasn't really my home and in my room on the desk i saw something like 4 grams of weed. That made no sense, because my parents were in the next room and what kind of moron puts something like that for everybody to see.I then remembered to perform a reality check and i tried to push my fingers through my hand, but that didn't work, so next thing i tried to hold my nose and breathe and i could! I knew i was dreaming, but i wasn't really convinced for some reason...and it was all blurry and stuff... i shouted "CLARITY NOW!" a couple of times but nothing happened, then i tried looking at my hands to stabilize the dream and that didn't do much about the clarity either, though i think it did manage to keep me lucid for longer. Another really wierd thing is that i could barely walk, it was as if i was drunk. I told the dream to show me something awesome, but it really didn't... i felt stuff changing around me, but nothing visual or anything more like a change in energy if that makes sense.. I tried to go through a door, to see if the scenery would change, but before i could do that i accidentally hit a light switch and everything went black, i managed to turn it on and everything was back to normal (This is the second time ever that a light switch worked in my dreams) Upon opening the door i saw the exact same staircase that i used to come into my home earlier... After that i had some talk about life with my sister and eventually i woke up.
Now i'd be really grateful if someone told me why most of the things i tried didn't work. Is it maybe because this is my first reality check induced lucid dream or maybe because of the fact that i was sleeping in and that's when i got that lucid dream?

Edit: Oh and from time to time my dream eyes, started to get heavy and i started to feel sleepy and when i closed them i started seeing things like thoughts, much like when you do that in the real life, i knew i could fall asleep easily, but i didn't because i didn't really want a dream within a dream or something, but is it possible that that would have made everything much more vivid or the opposite?

That's some crazy dream man. Pretty awesome that you could turn back on the lights, that's pretty rare for me too.

The way I look at dream control is like this - I go through this cycle a lot when I start to doubt myself and I lose power over my dreams
1.I ask "Will this work?" (it doesn't, because I'm asking if it will work and not expecting it to)
2.Something does work (like the light switch thing) and I realize how awesome I am
3.I get more Power because I'm awesome and I expect everything I do to work
4.power overwhelming!
5.I start to think, "hmmm, could I really be that awesome?" --> back to 1

That's my experience of it, I'm sure some adept will give you much better answers though

Oh, also, it's just me but sometimes when I fall asleep in a dream, I wake up in another dream and a lot of the times I will have lost lucidity. I'm sure it could have made everything more vivid if you believed it would though.

I'd say it's just that you're starting out. The more you lucid dream, even if you don't make huge improvements every time, you'll get better. I found when I lucid dream, I can't force myself to do something abruptly, because I'll wake swinging and kicking. Try it nice and easy, just going through the motions. A huge part about lucid dreaming control is your confidence. Your subconscious is at play when you dream, so even if your conscious mind is saying one thing, your subconscious won't respond as well to your half-hearted apprehensions.
Most of my clarity in lucid dreams just came through weeks of dreaming and baby steps in improvement. It might be best to work on control as a broad topic as you're just starting out. Clarity should step hand-in-hand with your ability to change the dream's atmosphere, conditions and characters.
Once you get better, or now if you want to be ambitious, you MAY want to stare at a single detail. Different things work for different people so search the web wide'n'far while you preform experiments. Saying "Chocolate candy cotton-silver web" might trigger something as well.
Or maybe it just wasn't a detailed lucid dream. You can't always have COMPLETE control, so you have to give it up sometimes, bro, and just go with the flooooooo'.

Thanks guys, now what i need to find out is why i could barely walk as if i was super drunk...

I used to have the problem with feeling drunk and unable to properly walk, too, to the point that I've had to sit down in lucid dreams before to steady myself, or ending up crashing into walls or on the floor, unable to control my body properly. After a while of this happening I tried to think about it and focus on why it might be happening and what I could do to overcome it. This might not work for everyone, but I took one lucid dream to focus fully on sorting this out, and I haven't experienced the problem again since.

The problem for me was that I'd get overexcited and try to move around straight away, forcing it but not properly focusing on it. When I really realised what was happening, it occurred to me to actually just stop moving for a moment. Standing still, I tried to calm and relax myself as much as possible while still remaining focused on what was around me/directly in front of me - not trying to make anything new happen yet, just becoming more aware of what was already there. Then I tried to become more aware of my dream body (whilst being careful not to start thinking of my physical body in my bed): as you can do when you're awake, I tried to sense every limb and muscle, working my way through my body. I tried to imagine it being steady and light. Then, slowly, when I did feel steadier, I tried stretching, and then walking forward. It was almost effortless, and now I felt steady and aware instead of drunk.

Again, I'm not sure if it would work for everyone, but it definitely worked for me and maybe it's worth trying just stopping and focusing when everything begins to get that way. Kind of like when you're a little dizzy in real life and need to just sit down and breathe for a few moments until it passes and things are more normal again. What the others said about doubt and taking it easy makes a lot of sense, too.

Light switches work in my dreams some of the time, too. That's why it's good to have more than one reality check as well as just being aware of the things around you and anything that's out of the ordinary. And the same with the finger thing - it never worked for me until I relaxed, focused on it completely and knew for sure that it was possible. Changing scenery and getting the dream to show you things will definitely come in time, but to begin with it really helps to focus on what's already there. Usually when I don't do that the dream just fades before I have a chance to change anything.

I've not personally tried falling asleep within a dream before because I find it too easy to get swept away by the dream - even just closing my eyes for a moment usually triggers a false or real awakening, though I have had a dream or two where this hasn't happened. The things I saw were very surreal, strange and vivid, but they faded within moments and I woke up. It definitely seems to happen more closer to awakening; perhaps it's still worth trying, though ^-^
