dreams bleed into reality

Sometimes I have really vivid dreams and later on I think little things that happened in dreams actually happened in real life. Actually that happens to me on a semi-regular basis.

Other times I feel strong emotions in dreams and when I wake up I feel like that for the rest of the day.

Other times I wake up from dreams within dreams and it's layered and when I wake up for real I'm not immediately sure if it's reality or still a dream.

And (although this is the most rare), once in a while I really, really feel that reality is a dream. Not in the fantasy "I wish this were a bad dream" way, but in a physical feeling that my surroundings are made up and from a dream.

Crazy! I think dreaming is amazing. Reminds me of this xkcd comic:
