Starseeds - Sirius B - Whales question

A kind redditor on this sub recently used my birth chart to see where I likely came from, and said Sirius most likely

I began reading up on that - and was amazed when reading about Sirius B specifically - as I LOVE Blue Whales - and although I avoid travelling (classic stay at home sensitive introvert) - I have one ambition - to see them out in the wild up close, from a boat

(I'd even want to swim near them - except I have severe OCD, and the oceans must be filthy - plus I don't fancy getting eaten by sharks)

But I am confused -

If Whales are associated with Sirius B - and if I am from Sirius B - was I a whale (or other marine life) out there, before coming to Earth as a human?

Or - is the association of Whales with Sirius B more symbolic?

Additionally due to my OCD - I keep washing my hands - and have VERY long showers - so much so that my mother often quips I must have been a FISH in a past life, as I seem to prefer water
