What bug is in my house?

Today I saw ten bugs (?) in my house, only at or near my desk. When I touch them they don't move at all so I'm not sure if these are even bugs or maybe something that falls off a tree or something, but its shape looks a lot like an insects'. I live in Poland with dogs and rabbits. I will be grateful for any help, I had bed bugs years ago and it was an awful experience so I'm really paranoid about it:(
