Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Gavin has had 4 dreams every day for a year now. If he had twice as many dreams last year as he had this year, calculate the total number of dreams he's had in the two years.

### Response:
Since a year has 365 days, if Gavin has been having 4 dreams every day for a year now, he has had 4*365 = <<4*365=1460>>1460 dreams this year.
Gavin had twice as many dreams last as he had this year, a total of 2*1460 = <<2*1460=2920>>2920 dreams.
In the two years, Gavin has had 2920+1460= <<2920+1460=4380>>4380 dreams.
