Sensory and quasi-sensory experiences of the deceased (SED), also called bereavement hallucinations, are common in bereavement, but research detailing these experiences is limited. Methods: An in-depth survey of SED was developed based on existing research, and 310 older adults from the general Danish population participated in the study 6–10 months after their spouse died. Results: SED were reported by 42% of the participants with wide-ranging phenomenological features across sensory-modalities. In particular, seeing and hearing the deceased spouse was experienced as very similar to the couple’s everyday contacts before death. SED were endorsed as positive by a majority of experiencers, and the experiences were often shared with family and friends. Discussion: SED are conceptualized as social and relational phenomena, which may comfort the surviving spouse in late-life bereavement, but also provide tangible help to some experiencers. In clinical practice, SED may be considered a potential resource for the therapeutic grief process.
