Hello, I am pretty new to all this concept of lucid dreaming, and I wanted to know one thing:

In the lucid dream, do you see as if you are seeing in real life? or is everything just kind of blury and you can obviously tell its a product of your imagination?

Also, how do you know if you had a lucid? Do you remember it immediately when you wake up, or is it like when you get drunk, you have a good time, then the next morning you dont remember shit?

I might be having lucids every week, yet I have no idea if they are actually lucids. Are lucids when you have control over your dream? or is it when you can clearly see and smell stuff?

thank you
