Hello Majda,
the healing peak is not equal to neuroception or VAKOGS, because it does not need a trigger to start it. It comes in the regeneration phase by itself and marks the return to autoregulation after the first counterreaction to the responses in the stress phase.
However, if it is felt as dramatic and dangerous ( = neuroception of our inner state), a healing peak can become another UDIN and a vicious cycle is created. This would be typically the case in heart palpitations or seizures.

So, to summarize: UDINs and VAKOGS trigger an autonomic response and organ reactions, these reactions can last and develop during the stress phase, until its resolution.
Then the regeneration phase sets in with typical symptoms of reversal, which often make you feel very sick. The healing peak comes without needing a VAKOG trigger, but it feels like a short reactivation of the stress because the energy is discharged. The healing peak isn't always dramatic, but it can be in certain tissues like ((Nervous - Motoric Innervation|nerves)) or the ((Circulatory - Coronary Veins (intima)|heart)). Then there is a danger of a new UDIN.
