No, there is no “normal” number of alters in a dissociative system. System size can vary considerably, ranging from only a few alters to dozens or even hundreds. Systems with hundreds of alters are less common, but they do occur.
The number of alters differs for each system because systems develop the parts they needed in order to survive their particular circumstances.
The number of alters in a system can also change over time. Some alters may fuse, which reduces the number of parts. In other situations, new alters can form if the mind experiences overwhelming stress. It is also common during healing to discover alters who were always present but had been quiet or unknown to the rest of the system.
