When I was in the neither my brother was in the normal world. Well saw something odd. I saw bubbles floating and dripping water and sounds like enemies in the normal world. When my brother and I experimented with this problem and found out that in the normal world where my brother was he could kill the enemies and I could see the death cloud pop up and they disappeared. Then when all the enemies were gone out of the normal world I saw my brother as bubbles and dripping water just like the enemies. I could hit him but he couldn't hit me or see me cause I was in the neither. I am happy to report this and help everyone that has this problem to.
