normalcy or no-rmalcy

how does one know what normal is when one does not have any basis of reference for feeling anything outside of one's consciousness and body?

for instance, yesterday, an ex colleague and I realised we both feel the same heart palpitations that affect us when sleeping. i used to think it was 'normal' or something that would go away, and so did she. But it has not, for years. It is only then that we realised that what we thought was normal is not normal at all. And this can well apply to any area of our lives—our thoughts, our actions, our feelings. Kinda scary huh?

And then another colleague was discussing another ex colleague and how she thought she was weird (ie. not normal), but stressed that she was "good weird". Again, what is this in reference to? the majority? the majority could be fuckin weird, and she could in fact be the normal one. hate such remarks. but maybe my threshold for weird is just very high. i dont know.
