There are also visual (see things that aren't there) and olfactory (smell things that aren't there) hallucinations ... Even some of our dreams can be a subconscience hallucination ...

Sometimes they are triggered by events that are happening in the here and now that are connecting to something from the past - even if we aren't aware of the connection at the time.



ps. Whenever mine happen now, I enjoy trying to figure out their source ... I enjoy the challenge of trying to piece it all together ...
