I just had my first LD today (i had some a few times in my life, but accidentaly) and acheived it through reality checks, it was amazing 
I started to get used to RCs in real life (looking at the hands and the digital clock) for 3 days and eventually did one on a dream.
I looked at my hands, one of them started to melt an the other only had 3 fingers 
i almost freaked out but then i realized “of course, it’s happening because i must be dreaming!!!” then i became lucid, like magic!!! I decided also to do the digital watch RC. I looked at it seemed to be fine, but i looked away an then looked back, and the time had changed. I did it 3-4 times, was actually kind of funny.
Then i started to do some of that LD stuff like flying, jumping high, telekinesis and so on. Hope it happens more times /o/
