The text presents a psychoanalytic approach of the migratory phenomenon of harragas using data collected from the mothers of young Tunisians who risked their lives to reach Europe. Our paper follows two analytical paths. On the one hand, it attempts to identify the unconscious motives which constitute this form of migration together with the maternal desire and the general mother-son relationship. On the other hand, we return to the disastrous psychic consequences of the clandestine migratory act (collective mourning, family trauma, etc.). These consequences are not only limited to the migrants themselves but affect the whole family and especially mothers.
