Well, here it goes.
1. The definition of WILD is to be aware while dreaming. So you may think you not asleep yet, but you just may be asleep already and dreaming.
2. One of the mistakes is to expect same thing happening during your WILD what you read about others experiences, or even what happened to you last time.
3. Visual HH can be geometric shapes or different random pictures, lights, blobs of color or just grey... at the beginning. Later, these may evolve into images, photographs and movies. The movies (dreamlets) are already dreams that are ready for you to enter.
4. Depending on how evolved were the scenes you are describing, they could have been HH, or already a dream. If HH, then yes, waiting just a few more moments while keeping your awereness would have lead you to a dream.
If it was a dream already, all you needed to do is realize it and enter it. You can find your own way of entering it, but this is how I do it:
1. When I see a dreamscape in front of me, I pick a spot in it and transfer my awareness inside by saying slowly and deliberately "I... am... there" while looking at the spot.
2. When I realize the dream has formed, I stand up from my sofa, or roll out. When I do this, only my dream body stands up and at that moment the feeling that I'm in a dream becomes even stronger.
For me, it was hard to remember what to do when I see the dream already formed. Because as you say, you were sure you are not dreaming/asleep yet. I took it as normal to see strange places, or even my room with closed eyes. So when WILDing, I adopted a mantra "when I see my room, I get up" which I later shortened to "when I see, I get up".
