Deja vu in dreams? Like... DURING dreams?

Hi everyone! So, today, i woke up from a dream, and as soon as i started remebering it, to write it down later, i've felt a strange sensation...
In my dream i had an iMac, although i have a PC in waking life. It was kinda strange the fact that it had all the applications from my PC... but more strange was the feeling of DEJA VU that it gave to me.

In my dream, i KNEW that i had an iMac FOR SURE in WAKING LIFE (and here i probably gained lucidity for a moment, because i differentiated the dream world from waking life ). And even minutes from awakening, i still knew that i had an iMac, and started asking myself where i could have put it. This feeling lasted for about ten minutes, then i knew it wasn't true.

It is strange that i kept this sensation from the dream... what are your opinions about it?

Something similar occurred to me when i was young: i dreamed about a peculiar landscape, and, once awakened, i've had a deja vu, like if i've alredy seen the landscape, even if i don't remember it. Did something similiar occur to you?

Knowing about real things within a dream happens a lot. Once in a dream I was lucid and started to think how could I know that I was actually controlling it, and it wasn't just another dream, so I asked myself about things I knew I had in real life, and realized that the next I had a spanish exam.

The deja vu feeling happened to me once. I was lucid and in a tabern, so I decided to go outside to call my dream guide. When I went outside I had to stop to examine the landscape. I took a sit and knew I had been in that place before, even though I had never seen it.

Deja vu is common in dreams. I have this theory that as your brain is spinning the dream story, it may find it needs a back story. A writer can do this by introducing a chapter that covers an earlier time period. Your mind accomplishes this by providing deja vu so that you "know" something from the past. I too have awakened and was sure for quite a few seconds at least that something I thought was true in the dream was true in real life. Eventually it dawned on me that it was a dream fact, not a reality fact.

That's a really good explanation.

I sort of had that feeling this morning. I woke up from a dream where Harry Potter and Ron Weasley went to a space program, and for half the morning I was thinking to myself, "I need to read that fanfiction again," when in fact, I've never read such a thing. (Would have been awesome to read though.) It was really strange.

It happened to me today. I woke up and I was through that I don't have to go to school because my mom told me it yesterday. After several minutes I remembered it was dream and I have to go to school. Very strange feeling...

Deja vu sometimes happen inside dream for me. And of course in real life too. Sometimes can be annoyingly confusing.
