Final answer:
Depersonalization is the best way to describe Danielle's out-of-body experience during her falling-out with a close friend.
Step-by-step explanation:
The out-of-body experience that Danielle is experiencing during her falling-out with a close friend is best seen as an example of depersonalization.
Depersonalization is a dissociative experience where an individual feels detached from their own body or experiences a sense of being an outside observer of themselves. It can occur during times of extreme stress, trauma, or anxiety.
In Danielle's case, the intense emotions and conflict with her friend triggered this dissociative experience, causing her to feel like she is watching herself from above.
