I guess you played the beats through your speakers, as your boyfriend heard them, in which case, they didn't work. They have to be played through headphones. Though the sounds might have helped your sleep in other ways, by creating a relaxing atmosphere or muffling external noise.
In any case, there are more tried and tested ways of inducing lucid dreams, for a beginner, binaural beats have very mixed results, and sleeping with headphones on is a pain in the ass. Have a look at the tutorial section for MILD and DILD, some of the most simplest and effective techniques there are. Bearing in mind everyone is different.
I wish you many more dreams!
