RolandJP, I slightly recognize this phenomena. Concepts or words revealing themselves in different contexts- emerging patterns. A problem with this 'hyperlinking' focus (which perhaps, could be plain pattern recognition hyped up on sex center abuse), is that it potentially could make you slumber harder by magical fascination. I agree with Anart that it sounds like you are applying this in a self-referential way (a bit like the tree 'magically' appearing over your head in that photo) like an obsession with syncronicities which we know can be tampered with externally and by our own deceptive minds. You don't mention any specifics only that the occurence is hard to word, which indicates you are not awake to what is happening, OSIT. This is where it would be wise to recognize the awake network's experience (Anart) in seeing a reoccuring pattern when it presents itself.
FWIW. My own recent pattern-loop is mainly based on 'grounding', a lessons-theme presented in dreams, representing itself in waking state in various reading and everyday situations, though I think that I'm making these connections more and more consciously, actively looking for them rather than subconsciously falling over them. I have also seen smaller syncronicities in seemingly unrelated articles as you mention but unless it relates clearly to the pressing lessons of cleaning my machine, I will down prioritize them as distractions. I'm not trying to say I don't fall for distractions, it's just the ones that are connected to a 'psychic quickening', 4D bleed-through kind of oddities I 'm really vigilant about, but still fall prey to older and yet unrealized patterns, these are prioritized when I can muster the courage to suffer their revealings.
If these key words are worth anything they should be able to be put to use, can they?
