Yes, you do. The mains supply is 220 volts, just like in Sweden, but all the sockets in Dubai are made for British-style plugs with three pins (pictured). So an adapter is a must.
Electricity adapters are sometimes available to borrow at hotels, but bring your own just in case. If you forget, they're available at the airport when you land and in lots of shops in the city, from minimarkets to malls.
Nowadays, USB sockets are often found in Dubai hotel rooms, sometimes at the desk and sometimes by the bed. They allow you to charge phones, cameras and similar gadgets without an adapter.
