It was my first really lucid dream. I was walking in this quarry like place looking for a way to get back to town when I thought to take my car. But then realized it was gone. I've had this dream scene so many times that it must have triggered the realization I was dreaming. That's when I said to myself I have to be dreaming. But it was all so real and I felt like how can it be a dream when it's so real? But I knew it had to be a dream. Then I saw this tree stump in front of me so I tried to make it grow some leaves or branches but nothing happened. end of dream. I think what triggered the dream activity was that I have a cold and had taken a good dose of nighttime tylenol cold caps. I hope to have more and better lucid dreams because of what and how you can benefit by using them.
