Weird spiritual experience

TLDR: I have this warm, heartbeat sensation in my head, was able to move it around and expand it to the rest of my body (struggled to get past waist) this was physically exhausting and throughout the ordeal I saw various images flash through my mind which mainly focused on eyes and a couple warnings and one focused on a mouth.

I also at a certain point felt like I was kind of drawing that sensation out of my body and when that happened I felt it in my whole body and that’s when I got the warnings. I can replicate this but it is hard as I am still drained from that experience. Though I only feel drained when I enter that state. I’m confused and a bit nervous and would appreciate any and all advice

For context, for my whole life it seems I’ve had this kind of heartbeat I could feel in my head if I focused on it. I never had any pain or anything like that from it and I always just kinda assumed it was just me feeling my own heartbeat because of anxiety so I just dismissed it.

Last night however, I decided to focus on it. What started with me being able to get into such a meditative state that I could hear music in my ears that I was playing in my head and then I start to realize that I could move it around my body. Not just move it, expand it. So I again, went into a meditative state and I slowly let it roll over me, enveloping my torso. This took several attempts and was physically exhausting tho that exhaustion goes away when I leave the state.

Throughout the ordeal in my mind I saw two images of weirdly anime men with a focus on their eyes, the first his eyes were these weird worm like cones in a spiral of yellow and black and the second was just a generic anime guy but the image was focused on his eyes. I also saw 2 or 3 images that I can’t really recall that felt almost like warnings. The warnings happened when I started to kind of draw that sensation out of my body.

After I was done due to being drained from trying to spread that warm heartbeat feeling though my body I saw another image in my mind, a black and white pair of lips that looked like the bottom half of a photo and then the image flashed and the eyes and mouth were there. It sensation never got farther than my finger tips though because I couldn’t push it past my waist, I wasn’t strong enough. I can replicate it but it’s hard now, when I try I get exhausted almost immediately and then once I get out of the state and calm down I feel fine. I would appreciate any and all advice
