Hippie Babysitters...

Many people have childhood memories of alien abduction, sexual abuse, trips to faraway places, and a host of other recollections of indeterminate veracity. Memories can feel true even if they are unconsciously manufactured. So... All I'm asking is, is it remotely possible that as a child growing up under the care of freewheeling hippie babysitters in the early 1970s, that I was fed an amount of LSD, or other such consciousness altering hallucinogen, on one or more occasions? Memory says, "Sure, why not?" After all, it would explain an awful lot!
