Has anyone had a Lucid dream before?

The first dream you describe sounds more like shared dreaming, not sure if there's a more official term for it. Dream control is often associated with lucid dreaming, but the definition of lucid dreaming is just knowing that you're dreaming within the dream.

Yes, I have. I've used the wake-back-to-bed method, and reality checks inside dreams. You might have read about it somewhere already, but I'll explain it anyway just in case and for anyone reading who doesn't know. The wake-back-to-bed method is where you wake up sometime in the early morning, get out of bed for a little bit (perhaps a half an hour) and then go back to bed. Because it's the early morning, you're more likely to fall straight back into REM sleep (the part of your sleep cycle where you dream) and since you've been awake and alert you're more likely to be more alert in your dream. A reality check is a simple trick to check if you're dreaming or awake. The most common one used, and the one that's helped me the most, is flipping light switches. In dreams, light switches tend not to work (though I had one seemingly snarky dream where they did, perhaps just my brain trolling me) and when a light switch doesn't work then you may realize you are dreaming. Most sites and people recommend performing reality checks while you're awake so that you eventually perform then when you sleep, but I find that just knowing something like light switches being dysfunctional in dreams helps me realize I'm dreaming because I flip light switches in dreams pretty often. I also keep a dream journal, I've kept one since I was 12. I remember my dreams pretty often and I tend to fall into lucid dreams without having to use a method just because I'm well-acquainted with dreams. Sometimes I realize I'm dreaming just because something totally out of wack happens, like the time I dreamed I was using the microwave and the microwave started yelling at me! So from my experience, keeping a dream diary really helps you to have lucid dreams on a more regular basis, but the best method other than that is the wake-back-to-bed method. For me that is.

Have you used any "strategies" in order to have a lucid dream? I think it's a goal for many to have a lucid dream but it can seem hard to achieve. I know it's hard for me to even remember my dreams every night. I could make the habit of writing in a dream diary but I just don't feel I have the time for it. But it sure would help, or so I'm told.

i was told today that it is a dream whicj you realize and can control your dream and can real captivate you and be amazing if you bid it

Well they can be powerful or memorable, and dream control is associated with lucid dreaming, but it depends on the dream and the dreamer. The definition of lucid dreaming is just having a dream in which you realize that you are dreaming.
