Colors?

I have question and I hope you have an answer. In my previous post I wrote about how I see spirits and everything but I missed something. I sometimes see thing but I don't know what they are. They look like spirits, have human like form but they have color. I don't know maybe it is a normal thing but whoever I asked if they see floating colors they say that no. I also was searching in internet about this thing but there's nothing. Sometime I see auras but not person. Like aura is surrounding invisible person. I'm confused.

For example I was sitting I'm my Friends room and suddenly I saw big something green floating in the air. I though it was spirit but I wasn't sure if spirits can have colors. I asked my friend if he sees same thing as I do and all he answered was that I'm scaring him. Yesterday when I was in the geography class I saw rainbow aura but it really wasn't surrounding anything. There are five colors I see red, green,yellow, purple and rainbow. I was seeing this colors floating in the air from little age but have always thought everyone could see that. Once when I was 9-10 I saw something green but big flying in the room. I was just happily looking at that because it was beautiful. Then it came down on the floor and stood in front of my grandmother. I started to laugh and said "grandma! You are all green!". She really didn't understand what I was saying but whatever. Its not only that I was seeing and am seeing them everywhere but I thought that everyone could see them. But now w

hen I asked so many people about that and they looked at me like crazy I got curious. Am I only one who see them? If you know that is that even if it have logical explanation pleas tell me ><
