I used to get these mainly when I was little. They were recurring then and very disturbing then and I had no idea they were likely uncommon so i n ever mentioned rhem so here i am now....i have an old sensation that is back. Can somebody please tell me they can relate or please explain what might this be? it starts out slow with a small blob or " sesame seed" {as my child memory would call it} then it accumulates quickly and moves a round with no sound and just gets a heavy over bearing feeling of doom in its presense then my hands and body feel swollen like they arent mine and i dont know what to do but try to escape it. when i wake fro the nite mare even tho i was only partiallly asleep it takes me some time to shake the thikness of the blob to feel my own finger prints and brain again
