Interesting idea
I like your idea. The spirit tries to seek out a new body as the old one no longer works. Yet due to it being damaged from death, it has difficulty doing so. If it does end up in a newly born body, it might not have the memories of a past life anymore.
"It is of interest to note that while some dolphins are reported to have learned English -- up to fifty words used in correct context -- no human being has been reported to have learned dolphinese."
Carl Sagan (1934 - 1996)
