My point of view probably won't be too popular but I'll bite.
You metabolized an extremely powerful psychedelic substance. People seem to forget that psychedelics radically alter your perception of things, though they may allow you to look at things from different angles or even look at yourself from a radically alien perspective, fundamentally, you have to accept that the way you got there was by taking an astonishingly powerful drug. Though the experience seems to contain a vast amount of meaning and depth, I think experiences like this reflect exactly what makes us human.
Maybe your mother didn't give you enough affection?
Maybe she did and that's something that has been deeply embedded in your psyche, and as an adult(i assume) you yearn for that maternal affection, even if you aren't aware of it. There's a good chance both of these statements are inaccurate.
I don't think it's too useful to ask other people to interpret extremely deep and personal experiences like this because we'll take an objective explanation like yours and apply our subjective experiences and thoughts to the information and interpret it incorrectly.
With personal growth should come good understanding of who you are as an individual, and understanding your own psyche is of the up most importance when trying to interpret your psychedelic experiences, we can't really decipher them for you because we aren't you, we don't know your history nor even understand how you experience emotion or lack of emotion.
Try not to get too wrapped up in applying meaning to these experiences, it can be exhausting. Maybe take one lesson from the experience that is clear to you and apply it in your everyday life and see how that works.
For me, deep "mystical" and "cosmic" states are just projections of my own mind, and it's like peering into the ultimate mirror where rarely, you may get a crystal clear look at yourself from a radically different perspective, which is why I think these experiences are beneficial to me. If a part of me I never "met" or knew existed is calling me out on my bullshit, or even praising me for my actions or achievements, or even spreading cosmic unconditional love to the core of my being, I recognize the brutal honesty in the experience and find it useful for me to look at my experiences this way. If I looked at my guides as "spirit guides" that exist separately and externally from me, instead of aspects and radically expressed components of my own psyche, I doubt I would take as much meaning from the experiences as I do when I look at them as being projections.
What's it mean to you? Perhaps nothing?
Welcome, by the way. Hope you have a good time with this stuff ;p
“The most compelling insight of that day was that this awesome recall had been brought about by a fraction of a gram of a white solid, but that in no way whatsoever could it be argued that these memories had been contained within the white solid. Everything I had recognized came from the depths of my memory and my psyche. I understood that our entire universe is contained in the mind and the spirit. We may choose not to find access to it, we may even deny its existence, but it is indeed there inside us, and there are chemicals that can catalyze its availability.”
