What is the difference between "Han följer efter mig" and "Han följer mig"? I’m asking because Google Translate gives the second one as the translation of "He is following me", and the English Wiktionary gives the following example sentence : "En gatuhund följade mig hem." (without "efter")
I'm not sure what you mean by "behind nor with nor side", but if you wanted someone to follow you and specifically stay behind you while doing so I would just completely rewrite the sentence to say "Håll dig bakom mig" ("Stay behind me") and let the following be implied by context, maybe after a simple "Följ mig" ("Follow me") if there is no context to imply following. There isn't really a neat, easy way to literally translate that sentence that comes to me right away.
