This happened a few days ago, when I shrugged it off, but after reading some more on LDing I decided it would at least be worth sharing. One morning I woke up very early in the morning, and as I usually do I fell asleep again immediately. It felt like 5 minutes had passed and I was in a daze, then I remember thinking to my self "I'm dreaming" with absolute confidence, and my heart jumped in excitement (or so it felt). I think it was a few hours later that I woke up. I don't know how much time really might have passed or even if/what I was dreaming. Any explanations?
