the most effective way to get an LD i think depends on you personally there are many ways try some and see which ones work best such as WILD DILD. for me i just do reality checks and write in a dream journal. the first time i tried lucid dreaming i immediately had a licid but i was only lucid for about 10 seconds so thats normal its a good start. and about the LD's and sleep paralysis from what i know i don't think just having an LD increases sleep paralysis
