For visualizing things I don't even really need to close my eyes I could just I guess you could call it daydream and just focus on trying to picture these things with my eyes open and it's like I could see both what my eyes see and what I'm imagining at the same time not like overlaid into reality or anything but just like two separate streams playing at once but giving time slicing to each with obviously more going to reality because that's kind of more important.
Edit: it's actually really hard for me to imagine that people can't do this and I've been working really hard on trying to not be judgmental against people who can't because it just seems so natural to me. And it's not like I'm psychotic or something or schizophrenic... I got my mental issues like long diagnosed ADHD since I was 2 years old but that doesn't disconnect me from reality in any way.
But I do know that there are some people out there who, are probably maybe fundamental religious people, who have a issue realizing that thoughts that they have aren't actually things that they consciously want to do... Like they judge themselves upon the sins that they think of in their mind. I find that weirder honestly. Imagine being haunted by judging yourself and your own moral compass upon the random brain firings that your subconscious has and brings to your consciousness. That's a self-imposed to hell that I couldn't even imagine, I mean they are just thoughts, learn how to meditate or something, let thoughts wash over you and realize that they are just thoughts don't try to push them down or silence them because that's not how brains work. Oh and also don't act on them but that shouldn't really have to be said. You're sentient being and you can filter what your subconscious thinks and what your consciousness picks up from it.
