I think I’ve accidentally found a new way to WILD. I don’t know if it’s new but I will describe it anyway. I usually WILD by “zooming” into HI and then I’m in a LD, but it’s hard to get stable HI that I can zoom into. And if I get HI I usually don’t get SP and if I get SP I only get HI if I can stay in it for quite a while. But I usually wake up from the SP before that happens.
But today and maybe 1-2 times before today I’ve opened my eyes as soon as I’ve reached SP and I was in a dream 
So the tech is very easy to do if you can get SP, just open your eyes and you are fully lucid in a dream 
And I guess that this only works after you’ve been sleeping for a while, I’m not entire sure about it though. Try and see what happens. I had SP atleast 5 times this morning and I opened my eyes during the last 3 times and I was in a dream. Once I was still in SP in the dream, but after a while of fighting against it I could move 
Good Luck if you try this 
And sorry if this isn’t a new tech 
how do you know you have reached SP ? 
I get intense vibrations all over my body. And I just happened to have SP too this morning, I didn’t plan it so it seems to be the same as your friend. I don’t know if it works if you voluntary induce SP. But I will keep trying and then I will edit my first post
