Welcome to Dreamviews~

I recommend you don't try to start with WILDs first, it is difficult at first. Try to get some DILDs under your belt first

When I remember i remember becoming lucid in nightmares as well, that seems to be a thing that triggers awareness, but yeah the dreams end soon, your first few LDs will be like that just learn to stabilize it and things with LDing will get better in time.

Try to figure out the dream signs like you said

and start keeping a dream journal for your recall, if you have any other questions, feel free to ask ~
