This dream is so interesting!

I am a newbie and still don't have much experience, except for a few spontaneous lucid dreams.. I, too, was very impressed to notice that sensations, especially vision, were so vivid and real; this is fascinating.

Sometimes there is some part of us that likes to ruin things... and, unlike reality, in a dream those thoughts immediately materialize.
I think that this is what happened to you; you probably found the experience amazing and wondered, even for a second, if you were actually supposed to enjoy it.
What I mean is that the subconscious has a big part in this process, and it doesn't always agree with what we desire! Sometimes it sabotages us.

Anyway, sounds like you are in a very good position now, and ready for more!

Good luck!
