Childhood Reoccurring dreams or Lucid Dreaming brought on?

Hello all
So when I was younger I had a few reoccurring dreams. The typical bad one , the one where its not bad but makes no sense, and then there was something I am not sure was a dream or me in some kind of LD, state of mind, or what.
When i was younger I used to sleep on the couch a LOT. Almost every night I would end up on the couch for one or more reasons. A lot of things would happen that I would block out or run to an escape in my mind as to ot have to deal with it. Now I don't remember this as a dream or if I was awake... but I used to be on the couch, except for the couch of course looked different and more imaginative but the couch was ALWAYS floating in what seems to be an outer space like atmosphere. Maybe with out planets and as many stars? But I would be able to float in any direction I wanted and see different things I liked or people I knew in a certain area and go to them other times I would just be at total peace floating around with no other thing or stories going on. Almost like a peaceful sleep but in a dream except I am not sure if I knew back then if I was dreaming or not. I do not remember. I remember being able to feel the actual motions of the direction I was going. Like physically but then again I do have severe vertigo and often feel as if I am moving.
My other dreams when I became lucid I remembered it and remember becoming lucid although back then I didn't know the definition.
This specific "dream?" would happen constantly! I can almost sometimes remember laying in the couch and making this feeling happen and I would go into that state again. Which to me sounds lucid but like I said I do not remember knowing if I knew I was dreaming or not.
I have not been able to go back to that happy place since I was a kid but I think about it constantly and I can see where I used to be in my head constantly. Its so frustrating cause I want that feeling back but I am not sure what it was!!!

As I mentioned in introductions I used to become Lucid when younger and now but cannot stay very long before waking myself up. I have also yet to have a controlled LD or induce it. I am wondering if my memory is so jogged that maybe I was lucid dreaming in control when I was younger but cannot remember because I blocked so much out. Someone please give me an opinion. :)
Thanks

The only thing I can say is for you to compare how the lucid dream feels with the "dreams" you had as a child in space. How do you get to that state? What are the sensations? If you were escaping to your mind from some bad things happening in your life as you say, it's possible to create an imaginary world. But I can't say, what was it. Sorry.

But the feeling of movement, flying through space or falling through your bed are some of the sensations you get when entering dreams.
