Given what you have been going through lately, I would be far more surprised if you had not had some kind of strange experience, dear!
I'm not the type to say.. wow, cool, you have had a major spiritual revelation.. or not without starting first from basics
I think it is fairly obvious, given your own personality and heart, as well as your background, that the psychism is starting to come through. The transition from child to man is generally a 'busy' time for these talents to come through and they come in fits and starts.. small tremors and great flashes. The physical problems you have been facing will leave you wide open to this, and the messing about with your spine and nerves could also enhance this effect. The drugs you have been given can also open doors between the levels of being, so perhaps you have seen more than you normally would have seen at this stage.
That you are a healer by temperament goes without question.. anyone who knows you at all can see that it is a genuine desire and need to help others with love that drives you Even through the recent crisis, you have shown such care for thers that I, and others, have been sooo proud of you, and humbled by the breadth of care and the courage you have shown.
I know you revere the Christ, so it is not surprising that the symbolism of His trials has resonated with you through your own. What you have undergone recently has been major, life-changing and drastic. It will, in many ways, give you the opportunity to define the direction in life that you take from here. The cross ( and the Swastika is aso a cross and anciently a symbol of Light) is a symbol of balance, equilibrium.. and that is perhaps what you need to find in yourself and for yourself before moving forward.
But with any vision or symbol, it is what they mean to yu personally that counts most, more than anyone else's interpretation.
The Atlantean/Lemurian connection.. well, we have discussed before the current theory that many who lived then have been reincarnated now. As the world stands, I feel, at a crossroads of opportunity, it may be that these souls have gathered to help the world take a step forward. To live as an example and be what you want to see is a magical act and spreads by touching the lives around you.
