You may still have been experiencing your Empathic Abilities.
Many Empaths are able to feel the emotions (sadness, sense or fear or grief, fear of dying, sense of shock, etc,)
However, this is where it becomes tricky.
If it felt as though you were there, as the pain was yours. Like you were one of the students, etc., that is called Clairsentience (Clear Feeling)
If it got to the point where you were able to pick up visions, hear voices, retrieve information, etc. that is when is it termed Psychometry.
I hope this information helped.
