One of the strongest lessons learned in my life is that everyone is not merely different, everyone is a lot different in many ways. Some of the differences are so dramatic, many of us will never even think that the differences could exist.
For myself, while growing up I always considered myself to be perfectly normal because I never knew that people were so different inside. But now, after decades of asking specific questions, and learning from the answers given, yes, I could verbosely-verbosely speak of specific details that dramatically distinguish one person from another.
What might indeed be true for one person, might not be valid nor so much as be comprehendible for anyone else.
With a very simple question of 5 words (3 words if we omit the article and preposition), you could see how dramatically different everyone is by how they answer the question. It's HUGELY different.
A brief example of being different:
At five years old there was a time of an unseen 'visitor' (I could sense his presence (long explanation), but I could not see nor in any other manner sense him with sensory perceptions). Each time that he was present, he never communicated to me, nor did he so much as acknowledge my presence. Nevertheless, during his visits I would perceive events that would occur in the future (I still keep a large database of important predicted events along with the dates of their occurring (all have now come true except the last one that will occur at or near my death). In time I began to refer to him as "brother".
Throughout the rest of my life, whenever brother was present, whatsoever I sensed would come true in later days, weeks, months, or years. Always 100% accurate, no flaws whatsoever. I was 43 years old before I finally discerned who or what brother was: it is simply myself sensing my own emotions from a different time period (sort of like vivid gut feelings but with extended details).
The moral of the story is that if a person speaks of having (or not having) a guardian angel or such, then it may indeed be true, as true as anything else in this world. The guardian angel might later be discovered to have been of a different nature, but the angel is still real. (I wish I had an angel; I'd be much better than talking to myself. 😉 )
I am SO very tempted to explain something easy and excitingly fun for people, but, nah, when the time is right, it is better that everyone firsthand discovers and learns it on their own.
