Why did this lucid occur?

I was in a dream which took place in my very own house, then it just randomly loomed on me that I was in a dream and decided to plug my nose then I was ecstatic I was lucid with little to no effort. A little less than a mounth ago i gave up lucid dreaming I use to be obsessed with trying and only had short little lucid dreams very rarely. Now im wondering did this dream occur because at randomised times of the day I told myself you are dreaming plug your nose! Look at your hands!!! Thanks guys. The dream seemed to last about 5 minutes which is currently my longest lucid dream.

Congrats on the LD!
In my own personal experiences, I've never actually become lucid from actually doing an RC; usually the lucidity comes and then the reality check, but sometimes I don't even need to do one. I always just become conscious right out of the blue; this is probably because, like you, I've randomly stopped during the day (which is a big part of my RCing/awareness regimen).

Also, if you take a step back for a moment and relax in terms of your lucid techniques, you'll probably find that it's easier to become lucid than if you make it a chore and think like you "have" to become lucid soon.

Thanks Puffin, glad your still active and posting because I remember you helped me a great deal with getting my first lucid dream. Quite interesting that it can happen right out of the blue, excited to see what dreams await me next :)

Congrats on the lucid! Keep it up!

Everything has a chance of happening in a dream, so your bound to become lucid now and again, by practising and experiencing lucid dreams you increase this chance, so stay motivated and enjoy!
;)
Well done on your LD.

Actually trying too hard and being obsessed to have a lucid dream is also not that good.
So it normal to have it on a 'break'. I had experienced something like that a few times, that actually when I stopped writing my dream journal, stopped doing reality checks and stuff I achieved lucidy.
Congrats, now you have new found inspiration to stick to lucid dreaming :) Breaks are okay and normal part of every work.
