Content: In a 2008 survey, 27% of respondents who had lost a loved one said they had this kind of "contact" experience. When people grieve for a loved one, many individuals will react differently: sadness, overwhelm, confusion, shock, and sometimes anger. Participants in the study must have experienced the loss of someone close between 12 and 18 years of age. The sudden loss was shocking to the majority; over time, there was change and growth in their outlook in life. The conclusive result shows a better positive perspective in life, their relationship, their well-being, and their perception of compassion and gratitude. Bereavement science
