I’m curious if anyone else has experienced something similar during the Om technique or Kriya practice.
I’ve been practicing Kriya-related techniques for a little over a year and was formally initiated through KYI earlier this summer. I’ve also completed most of the SRF lessons but ultimately was drawn to KYI.

I actually started experimenting with the Om technique pretty early on. I’m Indian and have chanted Om and different mantras for years, so I already had a relationship with the sound before beginning Kriya.

From the beginning, whenever I close or plug my ears during meditation, I hear a very rapid rumbling sound dot a soft hum. It doesn’t resemble my heartbeat, blood flow, or the other internal body sounds I’m familiar with. I come from a medical background, so that distinction is part of what made me notice it in the first place. It feels much faster and enveloping. If anyone knows shiva its like the shiva damru which is amazing because Shiva is my chosen deity.

What’s especially interesting is that the intensity seems to correlate with sensations moving up my spine. Sometimes during practice I’ll feel what I can only describe as a sparkling or upward-moving sensation through my back, and as it moves upward, the rumbling becomes more of a vibration.

A few times it has gotten so intense that I’ve started tearing up because the sheer sensation can feel overwhelming. When that happens, I usually remind myself not to fixate on it and instead relax into the sound and let it surround me. As I continue with different breathing techniques, the intensity l changes and becomes more manageable. Now it’s very subtle like a hum. there’s also a very physical vibration. If I have my fingers in my ears, I can actually feel my hands trembling or vibrating along with it.

But I’ve also noticed something similar even when my ears aren’t plugged. If I become very still and concentrate, I can l feel what seems like my entire head or brain vibrating internally. The first few times it happened, I genuinely wondered if there was a small earthquake because the sensation of movement was so convincing, but nothing around me was moving. It feels very specifically contained within my head.

It’s honestly pretty trippy, but strangely peaceful at the same time. I don’t find it frightening. There’s actually something comforting about it, and when it happens I usually feel very calm and content just sitting with the sensation.The rumbling itself seems to be consistently there when I listen for it. What fascinates me most is how its intensity changes alongside the upward sensations in my spine and the internal vibration in my head.

Has anyone experienced something similar in Kriya, particularly with the Om technique? I’d especially be interested in hearing how more experienced practitioners or teachers understand it. Did it change or deepen over time, and were you taught simply to observe it rather than engage with it?

Are inner sounds and synchronicities normal as meditation deepens?
I practice Kriya Yoga and Tantra within Sanatan Dharma, and I’ve become curious about some experiences that happen during meditation or seem to occur more often as my practice deepens.
Meditation for me is not about trying to produce an experience. I don’t sit down hoping to see something, feel energy, or receive a sign. I meditate to connect with higher consciousness and surrender to the moment as it is.

When I received my Kriya initiation, I was told that unusual experiences can be part of the journey, but they are not the destination. I understand the importance of noticing them and then letting them go. I am by nature an internally curious person. Part of being human is noticing when something unusual keeps happening and wanting to understand it.

The most consistent experience is a very loud, rapid vibration or inner sound during meditation. When I cover my ears, I can hear it intensely. It is distinct from my heartbeat or other bodily sounds, and I’ve been aware of it for a long time.

I also sometimes feel a strong upward movement of energy. When that movement happens, the vibration becomes much louder. It can be so intense that I once started crying, not because I was afraid, but because of how powerful it felt. This now happens during nearly every meditation.

There have also been some strange synchronicities:

- Early in my spiritual journey, I tried a small experiment. During a deep meditation, I asked, “Within the next day, show me a rose in an unexpected way.” That night, I found packaging from a chocolate rose in my assigned parking spot. This was in late March, nowhere near Valentine’s Day. My spot is inside a private garage, and in all the years I’ve lived there, I had never found trash in or around it. I have no idea where it came from, but the timing and specificity gave me chills.

- I see 11:11 and 222 constantly. It isn’t limited to clocks. I see them on receipts, license plates, my dashboard, books, and random numbers on my phone. It happens several times most days, often while I’m thinking about something important. It actually happened again while I was writing the first version of this post.

During one meditation, I suddenly saw what looked like a wheel or clock with shiva. I wasn’t deliberately visualizing anything. Immediately afterward, I did a tarot reading about an upcoming move and pulled the Wheel of Fortune very similar illustration to the vision.

Once, the thought “the alarm is about to go off” entered my mind for no apparent reason. The building’s fire alarm went off instantly afterward.
I’ve also been discussing or thinking about a very specific subject, opened an unrelated book to a random page, and found that same subject mentioned. One example involved a detailed Lord of the Rings topic appearing in a book that otherwise had nothing to do with Tolkien.

I’m not sharing this because I think these experiences make me spiritually advanced, and I’m not trying to hold onto them. I notice them, stay curious, and continue with my practice.
What I’m trying to understand is whether this is relatively normal as meditation deepens. Do inner sounds, energetic sensations, synchronicities, or intuitive moments become more noticeable with practice? Are they signs of increasing sensitivity or concentration, or are they simply experiences that sometimes arise and eventually pass?
I haven’t read much literature about this beyond the Bhagavad Gita and the Yoga Sutras, and I haven’t found much that speaks directly to this combination of experiences. I’d especially appreciate perspectives grounded in Kriya Yoga, Tantra, nāda, or other Sanatan traditions.
