I'm using a Nikon N65 SLR, how do I shoot a double exposure?

I really want to do a double exposure, can someone please explain how I could do this? Or if this is even possible? Thank-you so much! Your answers are appreciated.

Added (1). No, I don't have the manual:/

Added (2). But I'm sure I can look it up.

Do you have the user manual?

Here it is:

Butkus is a safe place to download. The instructions for how to do multiple exposure would be in the manual if the camera is capable.

I'm not sure about that exact model, but look for a tiny silver button near the film advance lever. Take your first shot, press the button while winding the film lever, and it will reset the camera to shoot over the same frame. You can do it more than once on a frame. Here's the master- click on the book covers for some samples.

Your N65 does have double/multiple exposure capability.

When making a double exposure you have to make an exposure compensation. For a double exposure -1 EV, for a triple exposure -1.5 EV and for a quadruple exposure -2 EV. You can also simply multiply the ISO you're using by the number of exposures you want to make. So if you wanted to make 10 exposures on a single frame and you're using ISO 100 just set your ISO to 1000 (the first line after 800 on your ISO dial). Just remember to set it back to 100 after you've made your 10 exposures.
