Welcome to DILD class!
It could be as you say, that your LD was so real that your RC didn't work.
Most common reason why RC doesn't work is because when people practice during day, they don't believe it will work.
When you do any RC during day, you expect it to work, because you expect to be in a dream, unless proven othervise.
RC should start with an awareness question, something like "wow, am I dreaming?" and you believe you are. Examine your surroundings and try to find differences between waking life environment and the one you are in at that moment.
Then you RC and you fully expect it to work.
Not sure if this is a cause for your RC to fail, but it's worth a try to add emotions to RCing and to really believe they will work.
Also, it's allways recommended to use atl least 3 different RCs, in case one of them fail.
Some of the best RCs based on ease of practice in a dream and success rate:
1. Looking at hands + Counting fingers - Very reliable
2. Nose plug - Very reliable
3. Thumb/palm - Very reliable
4. Gravity - Very reliable
5. Change something - Very reliable
6. Switches - Less reliable
7. Reading - Less reliable
1. In Waking Life (IWL) Look at your hands, palms up and notice details. Count your fingers. In dream, look at your hands. Do they look normal (color, shape, size, can you make your finger longer?) Count your fingers. Do you have the right amount? This is a good RC, because your hands are always there, IWL and in a dream and you can practice this discretely.
2. IWL - pinch your nose shut with your hand and try to breathe. If you can breathe, you are in a dream. Also a good RC, because your nose is always there, little less discrete to practice.
3. IWL - Try to gently push your thumb through a palm of your other hand. Pay attention to the sensation. Anticipate, that it will go through. In dream, do the same. If it goes through, you are dreaming. Good RC also because you don't have to go and look for them and quite discrete to practice.
4. IWL - Say, "If this was a dream, I could levitate" and expect to float up. Do the same in a dream. Good RC, you can do it anywhere and totally discrete.
5. IWL - Believe you are in a dream, look at something and say "if this was a dream, that [something] would be [different in some way]. And imagine it changing to what you said.
6. Try to turn on a light switch. In a dream, flipping a switch usually won't do anything. But people do report that they can turn on lights in a dream. And if there is no light switch near in a dream, you would have to look for one and waste your time.
7. Try to read. In a dream, you can read, but when you take a second look, it will say something different, or gibberish. Also time on a clock may have letters instead of numbers. But it can also look correct. And you have to find a clock in a dream before you can do RC.
Good luck
