Sounds like love bombing. My experience was more subtle but same basic deal. Exaggerated attunement leading to euphoria and disorientation. Worse still when input is given by clients or other therapists, with assurances that this is a normal part of "the process". It's ironic that psychologists talk about the dangers of love bombing in relationships, and yet see no problem with clinicians fawning over clients in an attempt to engender trust.
