How do I fix these certain issues?

I’ve been into lucid dreaming on and off for years now. I saw a video of it on my youtube homepage the other day and decided id give it another try. I read the subs guide to SSILD as thats been the method that appeals to me the most. Before last night I had only had 1 lucid dream before but I had another one last night after doing SSILD.

I went to bed at around 10 and set the intention to wake up during the night. I woke up around 3:15 (I checked my casio watch so I didnt look at any light). I stood up out of bed to wake up a bit more and it worked but I just stood there and my eyes were super heavy and hard to keep open. Im worried if I turn on a light itll be too hard to fall asleep again. I then went back to bed and started doing my ssild. I noticed It was taking me longer then how I used to do it which I would attribute to my success, i believe it was more correct. I lost focus a lot but would just restart the cycle. I did 3-4 short cycles and about 3 regular/long cycles. When I went to sleep nothing happened, I had a dream about zombies and woke up at around 4:15 slightly scared for a second but knew it was okay. I was then awake for quite a while as I had a lot of energy from that dream and was kind of restless. I eventually fell back asleep and had another dream where I >! Got scared of being chased and shot myself. !< after this I kind of just gained lucidity and felt the dream become slowly lucid, but it was around 6:00-6:15 (i wake up at 6:30) and I felt the lucidity fading. It didnt last long at all. I gained lucidity and was in my room, I tried testing it by spawning something in my hand and it worked, then I tried changing the scenery and I couldnt, I was stuck in my room and could only change what was outside the window, when I felt myself losing lucidity I realised I needed to try gain control and I think I tried spinning as I heard thats a way of stabilising your dream. It was really weird trying to move but I tried spinning and spun out of bed. Then I tried moving and I felt my real arm move and realised I was waking up.

How do I fix these issues? Stabilising the dream and I guess not waking up. I suppose it would be better if I became lucid earlier in the night? But that would be harder because the reason I become lucid is because im in such a light sleep.

Thanks in advance, I checked the rules and wasnt sure what to do about what I put in the spoiler. I hope its okay. There seems to be a direct correlation with me being scared in dreams and wanting to leave the dream in some way whether thats what I mentioned or a game pause menu that leads to lucidity. This is interesting as when I have nightmares I tend to just wake up when it gets too much and Im fine.
