For dormancy there does need to be a temperature drop and reduced photo period. The amount of a drop is what is in question. Freezing temperatures are not required but a period of lower temperatures, perhaps under 60, are needed to start the dormancy. As has been reported other places, dormancy is not "require" but skipping it requires special conditions and practices. It also seems to be dependent on the cultivar. Some do better than others. Refrigerator dormancy is required for those places where the temperatures never get below 70.

That would be cold enough. Typical indoor temperatures are higher than that and are not suitable for inducing dormancy.
