Hello Marwan!
I have been naturally DILDing for years- I'm 14- but they're completely spontaneous, no matter how weird a dream is I sometimes just go with it.
I'm currently practicing SSILDs.
Try repeating "I will keep my eyes closed" as a mantra while doing your WILD. If it still doesn't work, try something easier like a MILD or an SSILD.

Good luck!
