What is the name of this thing happening?

[Guest guest]

I read a post here recently about a thing that happens sometimes and I can't

recall what the name is - but I can describe it:

Person with lbd quite suddenly does not know where they are and when they

are told they are in their bedroom, in their living room - some place very

familiar - they cannot make a connection to the place? " It looks like my

bedroom but I'm not sure. " " It looks like my bed " " They look like my

shoes " " the pictures look like mine but. "

This happened the first time she woke up after a " nightmare " that she

couldn't get home and was calling for someone to help find her. As she

woke up from the " bad dream " she did not have that connection to being home

and it took a few hours before she felt comfortable enough that she was

really home and in her room with her things and family and could go back to

sleep. I am not sure if it was a bad dream or a hallucination but in any

case the result was she was not sure she was really in her room in her home

with her belongings surrounding her or even that the pictures on the wall

were of her and family.

Similar has happened when she is left alone short times - often while

sitting on the commode (she is not left alone very much at all, she does not

like it).

This has a name but I can't recall what it is. I'd like to know so I can

look up more information about it.

Thank you
