Is it normal to hear/feel digestion when lying down? happening a lot lately -- several seconds of gurgling noise w/squeezing sensations every minute or so. can actually see movement sometimes.

Yes: To help avoid this, wait at least 2 hours after you eat and then lie down if you want also chew your food well and avoid gas producing foods.

Bowel sounds: If you are not in pain, most likely this is normal. Bowel obstructions can increase bowel sounds. Visible bowel moments are not normal. You should be seen by a doctor to make sure there is nothing wrong.
