The best way to trigger them more often is to get in the habit of holding your nose closed and try to breathe through it while you’re awake. Obviously you won’t be able to breathe through it while awake but doing this enough will get you more likely to think to do it in a dream where you will be able to “breathe” through it and know your dreaming.
On the flip side I’ve found weed typically stops dreams, believe it’s due to affecting REM sleep.
I know you’ve been getting downvotes but just wanted to say thank you for voting PSL!
