Are Sam's visions, dreams, and signs all from Lucifer or is this a mixed bag? AND What does it all mean? It raises some troubling issues.
After careful thought I think I am now going with the multiple sender theory. I will concede that Sam's visions or random flashbacks to being tortured in the cage may be from Lucifer. If that is the case then Sam is in trouble because Lucifer can now randomly screw with Sam's head and he has no reason to ever stop. Lucifer will need to be stuffed back into the bag along with Amara the Darkness. Who sent the vision of Sam being calm in the cage with Lucifer? If Lucifer sent it means more trouble for Sam. Lucifer can hear Sam's prayers. Sam was specifically praying when this vision happened. It also means that Lucifer saw the future and he knew the warding on the cage would fail. It also means that Lucifer can cause things to happen on earth like striking fire to a bush. SO does Lucifer have all this power? I would so no. I think God or God's emissary saw the future and showed Sam he would be/ or could be calm in the cage. Likewise, i think that the dream/ visit from young Dad had to be from God/ emissary because it was so different, had a specific somewhat helpful message and came in a dream. I know we have discussed this a bit in the comments but I would enjoy hearing any further thoughts. SPNLIT
