Oh yes... It can be a pretty unsettling feeling. It takes me unaware and usually while I'm remembering old dreams - sometimes I'm not sure even it I'm remembering the dream I thought I was remembering - and then I get tangled up on whether it was really a dream. Its best to maintain a sense of humor about these things.
Yes all the time, that's why am always confused.
Many of times.
Yes all the time!
All the time, once I had a dream of waking up then going to the bathroom and woke up.. i thought about that dream then I went up to use the bathroom again and woke up to reality! had to make sure it was by thinking of feeling my heartbeat/looking at clock and stuff.. I LOVE the Dreamworld :)
