A witness may testify to a matter only if evidence is introduced sufficient to support a finding that the witness has personal knowledge of the matter. A witness does not have personal knowledge as to a matter recalled or remembered, if the recall or remembrance occurs only during or after hypnosis. Evidence to prove personal knowledge may consist of the witness's own testimony. This rule does not apply to a witness's expert testimony under Rule 703.
