I don't like saying "no, I'm awake, or not dreaming". I want to keep the sensations that yes, I'm.
1. I start with awareness question "wow, am I dreaming?".
2. Then I examine my surroundings, take note of details, while really thinking that I'm dreaming.
3. While keeping this "I'm dreaming" feeling, I do my RCs.
- look at my hands and expect to count more than 5 fingers
- thumb/palm - with all RC, you have to expect them to work, because you are in a dream
- nose plug
- levitation
4. Then, without saying, "No I'm not dreaming", I start saying mantra "Next time I'm dreaming, I look at my hands and realize I'm dreaming". Each time I say "look at hands" I raise my hands up and look at them, and I count fingers, as if I didn't know the answer, how many there will be.
Yes, it's good to do more than one reality check. At least 2-3.
If you normally sleep with TV, I don't think it will hamper your chance.
Don't forget to put emotions into your RCs and reality checks.
