So glad to hear your mental health's improved so much for you. Sounds life changing which must feel so liberating.
With the daydreaming, I've found there can definitely be many pros yet also some cons to this, which I'm sure you can relate to. Personally, I'm a massive daydreamer and my 15yo son has inherited his mum's trait. At the moment I have him seeing a neuropsychologist, because things have gotten a little out of control (yes, partly due to the influences of COVID lock down last year). As our GP initially touched on - While we're exercising this part of the brain mostly, we're not exercising the mental processing part enough at times. What can come about is an imbalance that can make it difficult to concentrate, mentally process things and so on.
The up side of being a daydreamer...hang on, let me rephrase that. The up side of being someone who can go into a state of meditation at the drop of a hat is...they have a natural ability to tune out from potential stress, the ability to trigger the parasympathetic nervous system (the opposing system to our fight or flight one), the ability to tap into the imagination with no effort etc, etc. It's such a shame we're not taught how to daydream constructively when we're little.
Personally, I've found there's some art to daydreaming. Give a couple of examples
- Half in/half out: When a friend's explaining to you a confrontation they had with someone, you can be hearing what they're saying while meditating deeply on the imagery, regarding how it may have played out. In your imagination, you may see something they didn't. Perhaps, in your mind, you imagine the other person becoming more and more agitated. You might then ask your friend 'Could you see the other person was gradually becoming more agitated?' Your friend may say 'Actually, yeah, I can see that now. They were'.
- Daydreaming/meditating on a challenge: You may be sitting there thinking 'I don't know what to do in this situation, I'm completely lost', before going into a state of daydreaming. You're not thinking, when suddenly what comes to mind is the solution. It either comes as an image of what you need to do or you might hear, in your mind, what you need to do next. Daydreaming can be a channel for inspiration
There are so many famous daydreamers in history. They're typically visionary leaders, inventors, composers, entrepreneurs and so on. Strong in channeling into natural inspiration and intuition, they also practiced balance.
