Was the experience recalled by my client [name withheld] of seeing a hawk in her house as a child, and also witnessed by her brother, a screen memory to mask the presence of an alien Grey?

This was a screen memory and was done through a Reptilian shapeshifting rather than the imposition of a false memory. So this was a distortion to create a state of complacency in creating the image of something that would hold fascination, and at the same time, delivering a mind control manipulation to captivate the imagination and to make the children complacent. This was countered quite effectively by alarms being sounded by the higher selves and this is why the memories are accompanied by disturbing feelings. This was the result of the higher self triggering some awareness of prior encounters with strange events that ended up causing great inner conflict and disquiet. Those reminders from the higher self became entwined with the memory of the visual presentation, and to this day, haunt her as an emblematic recollection of high strangeness in the events of her childhood, that were often terrorizing, without understanding the reasons why.
