I believe you can turn it around and use this as an anchor, I get the heartbeat sensation occasionally for sleep spindles, if you focus correctly you will start too feel like your moving , and will help be an anchor as it actively sticks you into the deep water quickly, it will destroy your focus to try and ignore this sensation, you have to let it come in waves and just watch as they come, don't pay attention to what has happened, but more too what is happening
