Just this morning I created a dream as an exercise ; I had woken up naturally and I remained in bed with my eyes closed. I pictured myself getting up from bed, taking a shower, getting dressed, and walking outside. The images were not vivid at all in the beginning, I could see them, but they were about as faint as a memory visualization from the waking state. I was completely unable to stay in real time -- my brain just kept on thinking about the end result so I had to "rewind" several times to avoid teleporting.
After a while I was able to sustain the (hypnogogic) images, and much to my surprise, unexpected things started happening. A girl appeared out of nowhere and there was a X,Y axis floating in the middle of the hallway. She was plotting points on it and creating lines between them, drawing polygons. It was like a flat hologram that you could interact with just by touching it.
What started as me replaying memories of a typical morning (with some difficulty) became hypnogogic imagery strong enough for me to feel like I was seeing it with my own two eyes, and then it became a dream that was beyond my control. I moved in my bed a little, and "went back" into the dream. I commanded the girl to get out of my dream and so she walked away, and I was able to continue.
After experiencing things like that, there's no doubt in my mind that hypnogogic imagery is an intermediate state between visualizing and dreaming ; the progression is nearly seamless.
But of course, that's not the only time we dream during the night... Supposedly it works in cycles of ~90 minutes.
