I've been practicing meditation for a few months now. At first, I found it difficult to clear my mind of worries and paranoia, as I find myself to be a rather anxious person (hence one of the reasons I decided to practice meditation in the first place). As time progressed, it became easier and easier to focus my mind on a singular "point" within my mind's eye. It's difficult to describe what I mean by that, but... When I focus on this "point," there is a kind of tingling sensation within the center of my brain. The only similar occurrence I can relate this to is the feeling you get when one of your limbs falls asleep. It's similar to that "pins and needles" feeling, but it's more pleasant and warm, as opposed to cold and annoying.
I feel as though that's a normal state of mind and body while in meditation. That's not the phenomenon this post is about, though.
With the onset of this tingling sensation, I often find myself in a very vivid visualization. I don't think about anything because my mind is blank. The visualization just comes to me without me having to think about it... If that makes sense. Another oddity regarding these visualizations is that they all appear in the same exact setting every single time, and I can't seem to relate it to anything in my natural life.
The visualization: It is always night. There's not a cloud in the sky, and the moon is either a crescent or full (typically full). The "ground" is not composed of dirt or grass, but rather an incredibly smooth, infinitely long, infinitely wide slab of seemingly unbreakable onyx which shines under the moonlight. Various colored (red, green, blue, gold, and white) sparks of energy (or perhaps flying bugs) randomly float about this endless, flat plane as fireflies would in a forest. Sometimes there is an owl, which flies across the sky, and usually in front of the moon. In a few of these visualizations, I have also seen what resembles the northern lights, but more of a rainbow spectrum than a mostly green one.
Would anyone have any insight to this? It seems like an odd "happy place," considering I've never even conceived something like it by myself. It's like the imagery just flowed into my mind while I was meditating once, and it's been reoccurring ever since.
Thanks for your input in advance :).
