If you're at your base (within range of bed and/or bench) for more than 46 minutes at a time, you get a chance of a random raid.

You say you're still in bronze age? Have you killed the Elder already? That's why you would be getting the Draugr and troll raids. The Drauger/Swamp raids will happen until you kill Bonemass. Troll raids will trigger at random once the Elder boss has been done and you've killed two trolls. Most raids will happen wherever you are with the exception of the Mistland mob raids which are now keyed to just a few biomes.

To be honest, if you're getting one raid after another within a couple of minutes, someone is on your server with cheat mods and they are spawning these raids in. This is the ONLY way it could happen that quickly. If you have mods running, ensure that these isn't a setting you've kept on or accidentally turned on.
