I understand you very well. I was the same when I first found out LD’ing is possible. Now, I hope this won’t let you down, but it’s how it is, or better said, how it was for me…
Don’t expect LD’ing to be a 3D videogame with no limits. Some are realistic and some are not, some are very real, some are blurry and foggy, some will be controllable, where you can do almost anything you want, others where you are stuck in one place not knowing what to do next… LD’ing can be a nightmare or an incredible adventure.
First LD’s will be a total let-down. You’ll feel very happy you had, it but if you look at it after some time, you’ll realize it was pretty foggy and “How could I have had fun doing that ??”. You may get scared in one of your first LD’s, especially if you get lucid right in the moment when this butcher chops you in peaces and you would want to get out the first second… People who have such realistic dreams are either naturals or people who worked like 10 years for achieving this stage.
Now, the positive part. In LD’s (at least in mine) you 99% feel yourself as “you” in real life. Every action you make will only be much more… “epic” to put it that way. If you will jump, you’ll get off the ground softly and land as softly back again, you eat tasty things like a chocolate but you’ll notice it has the taste of… water. All your senses are mixed up, even though the part of your brain which is responsible with dreaming (the SC) will try to make it as real as RL, but won’t 100% be able to. All this in other words, in a LD you as yourself will be the same as IRL “by default”, the thing that will cause you most problems is not yourself, it is the dream environment with I assure you, won’t be the same as RL.
You should therefor “work” every day on your LD’ing. I mean, writing down dreams, intentions, feelings, leading a LL (which is the hardens thing possible at first), waking up in the middle of the night, writing down fast then doing a WBTB or concentrating on a DEILD or even WILD…
Don’t expect you’ll get the “super-realistic-videogame-with-no-boundaries” for free (that is a the best kind of LD). You’ll need to train yourself somehow to be able to see if it is real life or dreamlife. Remember, the SC will always fail at projecting a full RL impression, but it has all the power you make YOU think it is RL.
But once you got a few LD’s you’ll see you’ll start to be slightly better, and you’ll want the next and the next. The secret is to keep trying how hard it may seem.
Good luck and happy (lucid)dreaming !
