What's the longest lucid dream you ever had?

Hey, its been awhile (2 years actually) since I’ve posted on this forum. Had two kids since then and had to put pursuing my ultimate goal of “Perpetual Lucidity” on the back burner while I tended to the needs of my “mini me’s”.

Speaking of kids, newborns get you up at all hours, especially around 4 or 5 am, after you’ve usually had enough sleep to pop you back into REM again after giving a bottle to the young’en (WBTB). I I’ve got to say thay I’ve actually started having LDs again on my own recently, somewhat spontaneously and without some pre-set intention. Now for the reason of this new thread.

What is the longest (to the best of your ability, since time is somewhat altered in our dream state) period of time you have remained asleep and maintained at least a tacit state of lucidity, if not full dream control?

I ask, because until last night/this morning, my personal best was 3 or 4 minutes, before the dream managed to wrangle control back from me and I returned to being a pawn of my subconsicous. However, my most recent LD lasted (what I estimate would be) nearly 45 minutes! I actually have vivid memories of myself in the dream doubting my lucid state again and again, thinking “surely I have woken up by now…the dream state usually destabalizes within a few mintues”. But each and every time I continued to do the nasal reality check (breathing in through my dream nose while holding it pinched shut with my dream fingers), I could still draw breath! So I kept on exploring, and got to really practice my flying skills with different approaches and stratagies, and it was truly great.

But I digress…I was shocked at how much longer this LD was than any one I had previous to date, so got to thinking…How long do some of your lucid dreams last (on average) and what is your longest that you have managed?
