You should stick with one technique. It takes time to have your first lol. Maybe she was just more aware. Thats the main thing that gets those DILD LD's. You should always have a back up reality check just incase the first one fails. Just check out some posts or something and search all day awareness lucid dream. It actually works. Maybe try so e mantras at night

For WILD, you can try FILD (Finger induced lucid dream). Move your index and middle fingers like you're playing a piano, but slow. It's best to try this using WBTB. Do a reality check maybe after 30 seconds of doing FILD after WBTD. It may be successful because you'd expect yourself to be in your bed
