weird baby body snatchers

dream: i can only remember bits of it, but there were eyeless, hairless babies that were climbing up on sleeping people and merging their arms and face into the back of the sleepers heads. this allowed them to take over their bodies. i had one get its' fists into the back of my head and it was about to merge the face but someone helped me yank it out. it was burrowed in like a deep tree root. what the hell?
