hi and welcome 
Adding to what the above posts have said, you can try to question yourself during the day (as another RC, I guess). Things like “where am I, does it make sense for me to be here?”, etc. I also would like to suggest writing down as much as you possibly can from your dreams (I type them out, tires me less). It can be a LOT of fun, actually. Record things like small details, shape, posittion, colors, feelings, etc. (more info here). Basicly, when I was at the top of my game in terms of recording things in my DJ (I used to get up to 7-9 pages on ld4all 
), I’d get lucid spontaneously and recognizing weird things in dreams was a lot easier. The more you write details down the more you get to know your dreams, the closer you are to them, so you start getting more aware while in them.
If everything fails, don’t worry. You can get lucid by many other ways. The LD’s in which I’ve gotten lucid through dream signs is a huge minority 
Good luck!
