That's okay, you can still make it work with less sleep, you just have to be extra aware while you're sleeping. It's tough for me to describe awareness in any other way than simply paying attention.

The best awareness technique I know of is to stare at the back of the eyelids continuously as much as possible while sleeping. In order to stare, 100% of your attention must be on staring. This makes this technique challenging to do, as many other thoughts often compete for the attention needed. If you're able to stare continuously enough while falling asleep, though, it's very effective because as much attention as possible while falling asleep will be on something related to dreaming. This helps maximize awareness.

Set your alarm clock only for the time you have to wake up to start the day. Stare at the back of your eyelids as much as possible while sleeping and see what happens. If you wake up from a dream, don't write it down, just keep staring. Watch the dreams come and go. This will help give you chances at WILDs by encouraging staying still upon awakening. Don't try to stay still or WILD, though. Just focus on staring forward with your eyes closed at whatever there is to stare at until your alarm clock goes off. Do this to exercise your awareness in order to make it stronger. Your meditation experience will come in handy here. The stronger your awareness is, the more dreams and awakenings you'll notice. The night will also seem longer as your awareness increases because you'll be more conscious of the time passing. I believe if you're staring all night long, you'll be conscious of a lot more than nothing. I know I am!
