The entire story of Beowulf is full of supernatural events. However, most of these events are pagan in nature and Biblical events alluded to in the poem are all from the Old Testament. Therefore, there is no real resurrection in Beowulf. The only thing "reborn"or resurrected is a building, Herot. However, some have suggested that in Beowulf's fight with Grendal's mother, the fact that he has to go deep into the sea and then re-emerges victorious suggests some kind of resurrection or baptism.
The supernatural elements are the major reasons for the events of the story.Tthe three monsters, Grendal , his mother, and the third monster who appears at the end of the story set up all the action for Beowulf. In addition, during the battle with Grendal's mother, Beowulf spies a sword blessed with the magic of giants and this helps him kill her. Finally, a fire breathing dragon who is aroused by a slave who takes part of its treasure, leads to the last heroic battle and death of both the dragon and Beowulf.
