A few times. I had a dream when I wasn't sure if something that I thought had happen in reality only happened in a dream (within a dream) or not.
I also think I had multiple layers of dreams and each time I realized "oh, this is still not it."

it happens to me a lot. recently i had a dream that i hid a book in one dream, then i woke up (still dreaming) and the book was under my pillow!

I wish. This is Twilight Zone stuff.

I have and I even remember thinking 'oh that is just a dream', go to a different level and thinking ' oh that is also a dream', so what the heck is reality. All in the dream.

I had a dream about waking up and telling my niece something, only to wake up from that dream to tell her about it, only to wake up from that dream to tell her about the dream within a dream, only to wake up for real.

No but I find the concept really spooky, instead I had some nightmares from which I couldn't wake up. Last time that happened, I was screaming inside the dream that I was trapped in my own head and couldn't get out, it was terrifying. /=

Can’t say that I have. Unless it was one of those dreams I can’t remember

I've had this several times. Have a crazy dream that wakes you up, only, you haven't woken up yet and you're in another crazy dream. That's when my brain starts telling me to actually wake up. Bizarre stuff

Always a first time
It's happened to me

No but I have confronted a marauding
monster in my dream and told it “ stop chasing me this is a dream”. The monster paused for a moment, then said “no it isn’t” then continued to chase me.

Not many times.

Yes many times

Not yet

Wasn't there a movie about this? Like having levels of dreams. With Keanu Reeves?

"They are not long,
The days of wine and roses:
Out of a misty dream
Our path emerges for a while, then closes
Within a dream."

--Ernest Dowson.

I’ve seen it in the movies but I’m not sure it’s happened to me.
What were you dreaming about?

A false awakening... Yes, only one, and it scared the crap out of me. I thought that all the crazy things that were happening were real, because I had just "woken up"...

I have had a lot of weird dreams but not that one, a dream within a dream.

I've had a few of those. It's disorienting but I like it somehow.

I've had dreams where I thought I had awakened but hadn't

Yep, it's on my Alan Parsons Prioject CD

Called a "false awakening" its definitely a strange experience. After you finally wake up, you wonder how you could have been fooled.

Yes, and it's very confusing/

am I having One now?

Many times.

Nice to know it’s happened to others. Maybe I’m not crazy 🤪 after all. lol

I have, and they usually result in nightmares for me for whatever reason.

It's happened to me a lot.

So many times

Nope! That's a new one to me.
