  1. In my dreams I____([color=red]can, could) fly.

I’d use can. For me even if those moments of flying are in my dreams, they still give me the feeling of they are really happening. Hehe. Looking for your opinions.

  1. I [color=red]can/could go with you tomorrow.

what’s the differrence in this case between can and could? Does the use of can express more certainty than that of could or is there any other difference?

Thanks.

  1. If you are talking about the dreams that you typically have (dreams that you had in the past and may well have again in the future), it should be “can”. If you are talking about some particular dreams that you had in the past, it should be “could”.

  2. “could” has a more tentative sense, as if making a suggestion.
