During a moment of creating outdoor illusion s ; heard a faint rumble of Thunder ; the air was still . Continuing the wind s started to gain power and there was also a coolness with another rumble of Thunder ; closer . Then oddly the rumble did not cease ; it rumbled and rumbled ; growing ever louder ; stopped and truly listened . The Thunder rumble was making large circles around and around ; also could hear it moving then off into the distance . Now , wind s are calm and all around are heard and movement about by bird s , animal s , insect s .
By the way the rumble lasted a good eight to twelve minute s ; non stop ; in a large circular motion . A cleansing of energy removing old thought no longer needed ? It was truly wondrous .

Hi Jimmy...
The thunder is a result of the sudden cooling of air. Lightning heats up air, it suddenly cools creating the boom aka thunder. Thunder is always produced by lightning. If you heard thunder but saw no lightning, it may have been the situation where the storm in which the lightning originated, was too far away for you to actually see it.
First off , thanking those that commented , thank you . But , there was one piece missing during this event , lighting , there was none to see during this time . Again many thanks to Light Being for the insights ; Feather Winger for the wonderful picture s and video ; and The Kat Came Back for you r humble word s . Be with joy and love always
Hi Jimmy....
Rolling thunder is caused by the rapid heating and expansion of the adjacent air, occurs either as a result of the time difference between sounds from the far and near end of a flash, or when mountains, layers of air, or other obstructions cause reverberations.
The original 'CRACK!' sound is echoing across the landscape. The second is that the bolt of lightning is significantly long. Let's say a bolt of lightning travels down 3000 feet from the clouds to a point a few yards away from you. You will hear the sound from the superheated air where the lightning bolt strikes almost immediately. The sound created at the top of the bolt will take longer to get to you, and by then it will be distorted by all the air it had to travel through to get to you.
Adding to this, the initial crack consists largely of high-frequency tones, as well some lower bass and treble, whereas the later rolling is mostly bass frequencies.
Lightning can go either from the ground to sky or from the sky to the ground. Let's say the above strike is from the sky to the ground. Then the thunder from the top will reach you before the thunder from the bottom, and you hear a drawn-out rumble, if it goes from the ground to the sky, the sound from the bottom has more distance to cover but is created first, so the sound all hits you more or less at once, and you hear a sharp, loud, clap.
You will notice that bolts that are really close (say within 1/2 mile of you) seem to have loud thunder that is shorter in duration, as this takes different amounts of time for the different frequencies to reach you. Lightning that seems to be some miles of your position, and yet the thunder sounds like it was rolling around directly above you.
The thunder can start soft and quickly grow to a loud clap followed by the rolling effect and ending with lower frequency rumbling. Again, the sound will seem to move around in the sky above instead of coming directly from the direction the original lightening. It’s a kind of Dopler Effect.
Not only does lightning have a significant length there can also be many lightning strikes down the same path within a short time. Next time you see lightning you may notice that it doesn't always just flash once, sometimes there are 2 or 3 flashes of the same bolt. Each of these flashes creates its own thunder.
The further away it is, the more chance you get of hearing the thunder from various different locations as it echoes off mountains, buildings, or whatever. If it's close you're hearing more of the direct sound and less of the ambient reverbed sound. Also remember the close thunder has a sharper "crack" compared to distant thunder where the higher frequencies are attenuated below audible levels long before the sound reaches you.
I live in a valley surrounded by the Penninines and deep rolling hills and when there is a thunder storm the thunder can roll continuously as the echoes go on until the next lightning strike. This can go on like this for a few hours.
Thank you for the in sight Light Being . It was a first for me to hear , see and feel this energy . Amazing . But, I believe there is more to this than just a constant rumble making a large circular motion and drifting overhead .
Thunderstorm like this, though not as often in UK can rattle on for 20mins or more, being near the Pennines we do see on occasions some magnificent storms.
I can remember a time when we had blue lightening streaking the sky, it lit up the sky for hours and no thunder, the air was warm and still and absolutely silent and it was awesome.
