In your hypothetical scenario though, the clone would indeed remember drowning and traumatize it. However, if someone were to tell him that the doctors "brought him back to life", he wouldn't have to accept his previous "death". At only 8 years old, it would be easy to convince him.
I'm not entirely sure an 8 year old would be traumatised by discovering that he was once dead, it's the same as once being not born, and an 8 year old isn't either scared nor, normally capable of understanding either, then again maybe, here is a brief train of thought on the matter:
(NOTE: I am not a neural scientist, the following is abstracted by my own understanding and simplified for the purposes of the explanation.)
A) The brain is a large neural network with segmented areas designed to cope with senses and motor neurons, but not entirely isolated from the whole.
B) Memories in the brain are structures in the neural network that are held by variably strong synapses between the neurons.
C) A child's brain is more susceptible to changes in the brain as it is still in the learning phase of human development.
Problem A) Can the human brain be capable of learning all the information of a past life without destroying the old brains memory?
Answer: The past memories would be all but destroyed with an imperfect 'copy all' technique for memory cloning, unless we gained the ability to selectively give the child memories the old memories would be gone.
Problem B) Can we actually mould the synapses of a different brain to gain all the memories of a past brain?
Answer: Brains are not all identical, the difference between one brain and the next will make this hard, it may take several decades to fully upload the new memories.
Conclusion: We need to learn more about how the brain stores memories and experiment with memory transfusion to fully understand this problem, perhaps training a rat to run a maze, and transferring that memory to a new rat who had never run that maze, then seeing with what success the new rat ran that maze would be a sufficient test.
