I had a LD this moning; I was using the kitchen sink to rinse my mouth when I noticed the details nearby. I swear I thought I couldn't differentiate the surroundings (of the sink) from real life. I went out of the front door to have a look at the neighborhood but it was a bit blurry. At that point the dreamscape faded and I woke up.

I don't know if this uncertainty is due to dream recall, since the dream is the third of a series I remember (albeit not in full detail, the first was a bit lengthy) and the last two of them were lucid. Did you experienced dreamers who now have real-life-like-dreams faced the same doubts when having your first quality lucids?
