>>11641046I used to be a five or better. I had an extremely vivid imagination as a child and was able to visualize pretty much everything including things like imagining constellations on top things I was looking at. I can still imagine things and walk through buildings in my head but now it's faded to level 3 unless I'm falling asleep. Sometimes I can catch myself entering a dream and then visualize whatever I want, but it will usually wake me up shortly after. I can also hear music in my head if I want to, so I can listen to music without actually putting on music, but only if I remember the song. Waking dreams used to happen when I was younger too, I'd spontaneously start seeing things such as rain or snow if I was zoning out.
As I got older it has gotten weaker, but I think it's a matter of training. Your imagination gets weaker if you watch movies a lot, read comics, picture books and play video games because you are no longer using your brain to visualize things for you. You are relying on technology to do it for you, so your "imagination/visualizing " becomes weaker like an untrained muscle.
Meditation is interesting too because you are deliberately depriving yourself of stimuli, so you brain has to look inward and starts creating its own images and sensations independently, but you can control it and steer it and make an entire place inside your mind. Much like the castle of memories some people use for incredible feats of memorization. Depending on how often you meditate and enter your dream-like state, the area you keep reinforcing in your mind by reminding yourself of the scenery every time becomes stronger and more vivid.
