Flashbacks

I know about acid flashbacks and stuff, but I was wondering if it's possible to get flashbacks from other pills. I've only taken ecstacy before, but today I was just sitting around, being sober, minding my own business when I suddenly felt this massive head rush kind of feeling and I was just totally tripping balls for about 45 seconds.

Did I just have a random mindgasm or could that be an E-flashback?

I like the idea of a "random mindgasm" personally

Sure it's possible. You can have a flashback to anything, it's not specific to LSD, or even drugs. You've heard of guys who were in Vietnam having flashbacks, I'm sure. I've had them of a car wreck. X flashbacks sound fun, wish I would have one.
