All i had so far is DILDs. I tried MILD the first time this morning, but didn't have luck. They say MILDs give you a 60% chance to have a LD. Well, i was in that 40% i guess.. I had a few exits right into Sleep paralysis though, so i guess it isn't that hard.
WILDs are hard, for me at least, cause when i try to do it, i either fall asleep, or reach a state where my heart starts to beat very fast and it throws me out of the "feeling heavy" state. And i'm completely calm, i'm not nervous about SP, so i don't get it.
So yea, MILD is better to start with. A dream journal is important.
