That is true that our five senses do not give us 100% true information about the world we live in. However that doesn't mean that everything we see is a lie. If everything was a delusion and all the information about the outside world was wrong then living organisms simply wouldn't be able to adapt, survive and evolve, because for that you need information about what's going on around you. If your eyes would give you completely wrong picture then you wouldn't notice a car coming at you and wouldn't step away. You may keep thinking that car is imaginary and it is not there, but that absolutely doesn't change the fact that it's coming at you and objective reality (in a form of car) is about to hit you hard. Sure, your eyes can't see in ultraviolet or infrared light, thus limiting you perception of the world, but that tiny spectrum that we use is enough to tell us that there is danger approaching.
Consciousness is not a reality, it merely mirrors objective reality. Sure, everyone has their own perception, but the real world out there doesn't care about that. You can imagine whatever you want, live in a world of delusion, but that won't change fundamental laws of physics that are quite real. And instead of deluding yourself why not study the world as it is?
