Well like you said, everyone is different.

I have a VERY hard time becoming lucid based on recognizing dream signs. Reality checks ALWAYS fail for me and I rarely notice things that are out of place enough in my dreams to have a DILD. I actually have had 2 dreams recently where I was telling someone about LDs and still didn't become lucid lol. Also some people, myself included, just don't have common themes in dreams. Mine seem to be fairly random and most are unlike anything I've had previously.

I would just stick to WILDing if it is easy for you. It's much more reliable than having DILDs anyway
