Creative Speculation

I often have dreams that I recall afterward. In a dream such as you describe, you may have been in an astral dream, one in which you can choose where you go and what you experience to some degree. I have had many of those over my lifetime, I have recorded several in a journal but I still remember them like I had them last night, even decades later.

If you find yourself in such a dream state again, try to guide your travel and experience by mentally or verbally defining where you want to go, you'll be there in no time and experience something amazing, at least that's how it works for me.
