No monsters spawning anywhere near my house in Minecraft (bedrock)?

No monsters spawning anywhere near my house in Minecraft (bedrock) I've tried everything from building a grinder in the sky to checking every inch of the caves below and can't find any at all Ever, if I travel a far distance I'll find monsters but with in a 400 block diameter or more around my house I can't get any to spawn, i'm not sure what the biome is but I have fields and small birch wood forests around my house

You are in peaceful mode, smart one.

That's strange, it's probably a glitch i don't know how you can fix it. Unless you have like a bunch of torches everywhere which is stopping the monsters from spawning but I'm assuming that's not the case.
