imaginary memories (idea)

I have three kinds of memories: Ones that I can't remember^A, ones that I can which actually happened^B, and the ones that I can remember despite them never happening^C.

Examples of A:

• First steps.
• First words.
• Seventh grade

Examples of B:

• Washing the night light
• Learning to roller skate.

Examples of C:

• The cactus that told me my mom was asleep. I was a young child, and one night I needed something while I was in bed. Could've been anything, a drink of water, a goodnight kiss, anything. So I called downstairs for my mother, but she didn't come. Then I called again, and a bright green half-anthromorphic animated cactus (with no eyes but a mouth) came up the stairs, stood next to my bed and said simply, "Your Mom can't come up now, she's asleep." In the morning when I asked her about her messenger, she just looked at me strangely.
