Questions about a lucid dream experience, help please!

So the past two nights i’ve had very vivid dreams, the first night was just a very vivid, lifelike dream like I regularly have. Last night was different, in each dream there was this little toy figurine of a girl with one leg broken off, in last nights dream I recognized the toy and immediately became lucid, the thing is, I didn’t do anything about it. I even reality checked by plugging my nose and breathing which I did successfully. After that I don’t remember being lucid anymore and actually had a completely different dream that was non-lucid. How can I make sure I take advantage of my lucidness in dreams, I’m pretty frustrated at myself for becoming completely lucid in a dream and then losing it. I don’t even remember how I lost it or if it was under my control. Any help is appreciated.

FLD ? or you simply lost it and need to stabilize it quicker.
