Congrats on the first lucid dream!
I agree with Nagirroc, next time you could try stabilizing first and/or using the engaging senses method. Though the reason it didn't worked might have been that you were at the end of the REM, so it still worth a try.

Any idea why you weren't excited though? Were you excited when you were thinking about it before?
