If you do not believe this, go watch Hummingbirds for a time and you will notice that these tiny creatures think, feel and have individual personalities and quirks far beyond what could possibly be contained in their small brains. This is because like us, they too are manifesting their spirit into this physical reality/world, just like we are, just like every creature. All that lives is far more than what we see and experience in this dense, physical plane. The fact that our consciousness is not aware of all that we are and have been is a far more complex subject I am not going to even begin to try to explain.
Sudden, out of phase/untimely deaths that happen outside the natural order of life and death for each individual causes a number of problems/confusions for the spirit. At minimum, the spirit will tend to hang around because it is not its time yet to move on to its next phase. Man exists on this planet outside the nature order of things because none of us/our spirits were created on and with this planet, we all came here/were brought here from elsewhere. This too is a complex reality I am not going to attempt to explain what I understand of it.
However, I can predict this. Those who were killed, for example, during this Tsunami in Japan will be hanging around until the time of their natural deaths arrive and then they will move on. Some will hang around afterwards because they will simply get lost and be stubborn about clinging to their existence in this higher/non-physical frequency/dimension.
We are surrounded by living beings/creatures that exist in higher frequencies/dimensions...they swim in the ether we all exist in and from which physical matter is created.
