The Dream shutting down?

This month, I broke my record of 2 lucid dreams/month, with four lucid dreams...
I also had the longest lucid dreams I've ever had, but the thing is, sooner or later, the lucid dream would just turn into a void, but I don't wake up, but find myself in another dream instead, not a single hint of lucidity...
Luckily for the last one I had, I repeatedly did my RC (nose plug) everytime I was in another dream scene, I was just lucky. I don't recall this ever happening to my past lucid dreams, but how do you think I can prevent my dream 'shutting down' and restarting?

Try to remain more aware in your dream. It sounds like after you lose lucidity your dreams just change. I'm not exactly sure why that would happen because I've never experienced anything like it.

Could you elaborate more on the void?

it's like closing your eyes, there is nothing before me, nothing around me, my dream body isn't even there anymore. Then in a split second, another dream continues..
I've heard of people waking up when their lucid dreams fall apart, but for me, another dream will just take over... but I guess that's a good thing.. haha...

You remain long enough in the dream for it to change. Just try to tell yourself to RC no matter what when you feel the dream slipping. If you stay relaxed and intent on keep on dreaming, you will either end up in Sleep Paralysis and you can DEILD, or you will end up in the void and another dream will soon start. It's a good thing yes! Just accept the dream can't be stable anymore and let your mind create another awesome dream scenario for you and keep on having fun ;)

I had a problem similar to this last month. Except for me I would go straight into a lucid and it would instantly start fading away into me just going to sleep. I would panic and try and ground myself into the dream but it would still just go away. I realized panicking was what made it go away. Then the past week I've had much more success. I believe it was do to my stress in my daily life. I had a lot if exams that were making me stead out. This may be just a phase but I cam only say from my personal experience that taking care of my daily life solved my my problem

Thanks for the replies...
Hopefully this month I could have more lucids so I could try to fix it... :)
