No. Berkeley believed that a belief that something exists is justified if and only if the object at issue can be perceived by someone or something, and if so, then the object must be just a collection of ideas; ideas that we all collectively perceive to be true and real. Therefore, we must accept the fact that there are no material objects and just a collection of ideas, which made Berkeley an immaterialist. According to Berkeley, only ideas that we perceive directly are real.
Berkeley maintained that objects exist only in the minds of those that perceive them. His main point was that objects cannot exist without being perceived, but he did not suppose he was the only perceiver. He believed that as long as some thinking being perceives an object, it truly does exist. Therefore, if I am staring at a tree and decide to close my eyes, although I no longer see the tree, it continues to exist so long as someone else is perceiving it.
Something that is imaginary exists in one person's mind alone and continues to exist only if the person continues to thinks of it. But if something exists in many minds, it can continue to exist whether I perceive it or not. However, once nobody perceives the idea of an object's existence, the object ceases to exist.
